Reddit mentions: The best envelope mailers

First class mail package/thick envelope works absolutely fine with 4x8 bubble mailers. It costs about $2.67 if you purchase the postage through eBay, and you get the added bonus of free tracking and delivery confirmation. When you're shipping more valuable cards, you might want to spring for insurance (pay out of your own pocket if the buyer didn't request it specifically). It's pretty cheap and is a good way to play it safe.

 
Here's the method I've used for shipping hundreds of cards on eBay, with absolutely no problems whatsoever. You'll need the following supplies:

 
#000 4x8 Bubble Mailer
Penny sleeve
Toploader
Team bag
Scotch tape
Packing tape

 

1. Place the card you want to ship upside down in the penny sleeve, then fold the excess bit of plastic back up from the open end of the sleeve. This will keep the card from sliding out of the penny sleeve.
    
   
   
2. Slide the penny-sleeved card into the toploader, starting with the folded end of the penny sleeve. Be sure to keep the penny sleeve folded while you do this. It might be a bit tricky to get the card into the toploader, but it won't fall out of the penny sleeve once you do.
    
   
   
3. Tap the bottom of the toploader against a hard surface a couple times if need be to make sure the card is all the way inside and level. Then, tape a piece of scotch tape and tape up the open end of the toploader. Make sure to use a bit longer piece of tape than you need, and fold on end over itself to make a tab on one side of the toploader. This will ensure that the card won't fall out of the toploader during shipping while making it easier for your buyer to get the card out.
    
   
   
4. Place top toploader inside a team bag and seal it. In the event that your bubble mailer gets wet, this should ensure the card remains undamaged.
    
   
   
5. Print out the order invoice, fold it up, and place it inside the bubble mailer along with the toploader. Seal the bubble mailer, then place a piece of packing tape over the flap of the bubble mailer to ensure it stays shut.
    
   
   
6. Print out your postage. You can use a regular piece of printer paper if need be, but I'd definitely recommend going with an adhesive address label. Better yet, if you'll be shipping in volume I'd recommend getting a thermal printer (I've got a Dymo LabelWriter 4XL that's awesome), because then you don't have to worry about smudging, even if the address label gets damp.
    
   
   
7. Apply the postage to the outside of the bubble mailer. If you're using regular printer paper, be sure to tape all edges with packing tape to ensure it stays in place. Then place a piece of packing tape over the addresses. Again, this step is unnecessary if you invest in a thermal printer.
    
   
   Hope this information helps anyone looking for a worry-free way to ship cards!

how many are you looking to buy? I got a pack of 50 from Amazon for $6. These were the ones I got and I guess the only thing I would note about it is that it's definitely a small mailer. With a pack of clamshell wax tarts, there's probably enough room for one more 10 mL rollerball comfortably. I can shove more in, but these are definitely small. I like them for sunday destashes though since most people don't buy too much so 95% of all the orders fit in there. With larger orders, I recycle the padded mailers I get. You can probably get more for cheaper if you look around, but I like Amazon so.

Edit: Oh and get packaging tape. That's the only acceptable tape. I found that out first time I tried to mail something haha. With those mailers, I don't use packaging tape though because they have a seal, but it's nice to have around. Last tip: addressing. You might already know this, but I didn't before and I messed it up two separate occasions before I remembered. Your address (the "from" address) always comes first and is on top. The address you're shipping to is on the bottom. I kept mixing them up when I first started mailing things because my logic was that you'd want the "To" address on top because that's the more important part right? Nope. "from" address is on top. These days, I put my address in top left, address I'm shipping to in the middle, but sometimes I make a label from notebook paper and for those, I just stack the addresses vertically on top of each other with my address on top.

OOOH OOH I HAVE TO ENTER THIS BECAUSE I HAVE THE WORLD'S BEST BIG BROTHER. I am the child of Indian immigrants. My big brother is 6 years older than me and we both grew up here. So, there is a huge cultural gap between us and our parents. I can't tell you how good it is to have an older sibling when dealing with that. I have no idea how he went through it all basically alone. When he was a teenager dealing with American teen things and Indian parents who didn't understand, I was just a little kid. When I was going through it, he had my back. He has always had my back. I have always been able to talk to him about everything. Even gross girly stuff and talking to him about crushes I've had on boys. He wasn't jealous or scared of me being born shortly after he turned 6. He was excited and he loved me and played with me all the time. He has always taken care of me. I know true unconditional love is what I get from my brother. He would still love me if I was a homicidal maniac. And I don't think I can live without him.

now I'm too busy thinking about how awesome my brother is to go through my wishlist so if I must post something from it I supposed I'll do that later.

EDIT: pics :D (ps I have no idea what that third image is or how it got there. I don't know how to imgur...)

I can't tell if you already picked a winner but I forgot to post what I wanted so here. Those bubble mailers will help me with my business because I'm going to launch soon and I'm offering free shipping foreverrrrr. But yeah, I really want this jewelry business to work out and this would help :D

As a seller I make sure I am fully stocked and organized with all the appropriate packaging so when I do make a sale I can quickly wrap it and mail it out. I purchased all of my supplies from Amazon! I use pink tissues paper, patterned poly mailers and thank you cards from Amazon and they basically have paid for themselves. I also purchased a shelving unit from amazon that I have all my tissue and boxes and mailers stocked on to keep everything organized! I just like to have my items folded and wrapped in tissue to keep them protected and I think a thank you note is a very sweet and easy gesture. I also buy on Poshmark and am sometimes a bit grossed out when I receive an item that is not wrapped in tissue or wrapping at all and I receive it all wrinkled. I constantly order clothing online and most retailers always wrap the items inside the poly mailers, I just think of it as standard. Hope this helps!

You are both look down right FABULOUS! And thanks for doing this!!

Gift One: This Cricut mini will help me make professional looking packing for my jewelry at home. I'm trying to startup my business and this would really help show my customers (when I finally get some!) that my commitment to quality started with the jewelry itself, and continues all the way to their door.

Gift 2: C'mon...gimme mailers for mailing out orders!

You guys are the best!

Where are you located and how many do you need? We designed our own box that fits an Ultimate disc perfectly and have them manufactured at a local box company. You can have some if you happen to be close enough to pick them up.

For shipping USPS will be cheapest. I hadn't heard of shipping a disc without packaging, but sounds awesome, ha! If you're not worried about bending I'd recommend at least put a poly bag around them to avoid scuffing. USPS can be pretty rough with packages, so we always ship a disc in a box. Some postal workers like to try to jam discs in mailboxes, so if you go the poly bag route, at least write "Do Not Bend" on the package.

They don’t really match but I’ve received a ton of love notes from buyers who love my packaging. :)

Use [salecalc] (https://salecalc.com/) calculate profits and fees.

Calculate shipping by weighing item + plus packing materials. You will need either a shipping scale or kitchen scale to determine weight. Choose "calculated shipping" when listing using the item's weight with packaging and it's dimensions. If you are going to sell clothing I recommend buying some [poly mailers] (https://www.amazon.com/gp/product/B000HG8720/ref=oh_aui_search_detailpage?ie=UTF8&psc=1) since they are lightweight, cheap, and great for mailing clothing items. I also recommend ordering some FREE padded flat rate envelopes and some A2 boxes from USPS.com for shipping items Priority Mail that are greater than 1 pound.

You can get a 50 pack of bubble mailers on amazon. These perfectly fit one deck in the original box. Ship via USPS first class for $3.50-4! Profit.

Edit:50 not $50 😂

Wow, that's a badass deal for someone doing a lot of selling. Bookmarked in case I need it in the future. Shipping of those does add up.

Quoted a #000 and a #2 shipment, with shipping came to 5.8 cents per #000 and 14.1 cents per #2.

For reference, I bought this and this shipped free using Amazon prime.

Works out to 7.5 cents per #000 and 32 cents per #2. Still have plenty of both left. Putting this up there as a less up-front cost alternative for someone doing less shipping.

Thanks again for the link though. Good info.

I sell through amazon and this is my Storefront

I keep it nice and simple:

• bags for shipping
  
  

• Stamps subscription per month: 15.99 (I should probably cancel and go to the post office. I am not sure about the cost benefit of it.
  
  
• Amazon subscription: 39.99
  
  
• supplies (1000 cases): ~400 bucks
  
  
• actual shipping: .92 each
  
  
• selling price: 5 a pop
  
  5*1000=5k
  
  5k-400= 4600
  
  3 months of amazon prime and stamps= 40x3 and 15x3= 165
  
  4600-165= 4435
  
  actual price of shipping for 1k cases is 920
  
  4435-920= 3515.
  
  referal fee varies i say .50x1000=500
  
  3515-500=3015
  
  grand total of 3515, assuming you sell everything in 3 months and assuming you are starting new without clientelle
  
  
  EDIT
  
  If anyone is curious as to why my prices are .01 each is because of sales and shipping. Since business is REALLY slow right now (maybe iphone 4 cases are too saturated in the status quo), i only sell ~30 cases a month. So upgrading my sellers account is not worth it. When I sold ~100+ it was definitely worth the upgrade. I can no longer be a featured seller and I can no longer manipulate my shipping cost w/o upgrade, this means at .01 + 4.99 shipping I can still sell them at 5 a pop and save 40 dollars a month.
  

I did 8-12 a month for the first nine months or so with revenue after fees between $120-250. June and July were super slow and I was on vacation for a couple of weeks.

Things have really taken off since December for whatever reason, I have been averaging about 20 orders a month and revenue has jumped as I have had 3 orders over $150 (thank you rey's quarterstaff) and two $600 orders, so about $2500 of the $4000 I have made has been since December.

Shipping helps and is super easy and cheap too, I buy these http://www.amazon.com/gp/product/B000PE46I8 and can ship most stuff people order within the US for less than $3. A project that takes a whole spool of material and pays $200 ships for about $6

I like to do some trading on /r/gameswap but right now I'm pretty tight on money and when I have to go to another store just to buy padded envelopes, (they never seem to have them at my local post office for some reason.) Anyway I ride my bike around a lot to do this all and when I have to pay for shipping and envalopes at a store that sells the for $1 each it gets kinda expensive when it stacks up with shipping, so all I'm asking is for some of these! :) (Also if I get picked, please don't spend the whole card on me, I just need these things and the rest of the card can go to someone else!)

I lug around a big BUBM Bag around to airports and the like. Domestic flights in Thailand charge extra for the extra bag. Airports are not delicate with the bag and I'm surprised nothing other than various parts of the case are broken. On the international flight I use instapaks to protect the insides as much as I can. On domestic flights I just pray for the best. My monitor is a massive 27 inch Asus regular montor. I had a ROG Swift 165hz monitor that an airline trashed a year ago; havent had the heart to buy it again.

Only tips I can give is have only a bit of clothes and get insurance whenever you can. Triple wrap with bubble wrap whenever you can too.

Here's a pic of my setup atm. Excuse the jankiness lol.

Oh and for specs:


GTX 1080ti

i7700k

1TB Samsung EVO SSD

z270 Taichi motherboard

16GB G Skill 3200MHz ram

OMG you can totally still decorate mailers and bubble envelopes!!! Any stickers/decorations I use for them I'll apply a thin layer of modge podge to make sure it stays on.these are some I've sent and received https://imgur.com/a/ikAnNTZ I also bought these ( https://www.amazon.com/dp/B07CZ264YB/ref=cm_sw_r_cp_apa_i_pLDyDbBDYBGHY ) adorable polymailers on Amazon and they have many others! :)

I think this is great. I hope to run across one in the future. So I thought about how I would go about this for maximum ease of return.

Supplies:

• Cameras (this style kind of important to my plan)
  
• Plastic Mailer Bags
  
• Film Canisters
  
• Printable Postage Stamps
  
• Cord/twine/string, Sharpie, small drill/pointy object, zip ties, and booze (for yourself and/or helpers)
  
  Work:
  
  Weigh the camera and one plastic mailer with your drug kitchen scale. Use that weight and the farthest US city from you (contiguous US only?) to calculate a maximum shipping cost with the USPS. Enter all that info into Stamps.com and print out the required number of printable stamps (don't forget to select the option for irregular or non-machinable item to include $.22 surcharge). Self address the mailer bags and write instructions on the outside of the film canisters. Poke or drill out small hole in top and bottom of the film canister. Thread string through and tie knot at end of string on bottom. Lay one postage label against inside canister wall and pack mailer bag inside. Close top and knot again to hold lid securely on. Strap a zip tie around camera between bump outs for lens and camera roll and between button and counter. Tie film canister package to camera using the zip tie.

uh oh, flat rate? yeah, then you have to go that way

I use these for probably 300+ swaps on reddit and 250+ sales on ebay, never a problem. if dealing with high volume, 4 for a buck is awesome. if you buy less, like at a Dollar Tree, they are 2 for a buck

I have shipped a few thousand books and have found the cheapest and safest way is to use bubble wrap and poly-mailers. I usually buy the wrap at sams club because shipping is too expensive online to get it anywhere else and the mailers from Amazon. This size is best for the widest range of book sizes.

Add another ~$0.03 for shipping label costs (ink, paper, etc.) The nice thing about this method is it is very fast to pack and I have not had a single issue or complaint.

Well, here is what I would recommend:

1. Use painters tape on your toploaders. Doesn't leave sticky residue and comes off easily.
   
   
2. Include a printed packaging slip.
   
   
3. Ship your orders that are easily in excess of $20 using paypal shipping labels. Not only does it save you a drive to the post office, it is actually cheaper as well. Ship from here and select the first class option for "service type" and "package/thick envelope" for package type. List the weight as 3 ounces, which I guarantee you will be under for shipping singles.
   
   
4. Buy envelopes, and use the mailer setting on Word to have it preprint your name and address on the upper left, and copy/paste their name into the recipient field. Use these for the <$20 orders along with a stamp and a prayer.
   
   
5. Buy bubble mailers off Amazon in 50 packs, for the $20+ orders. Something similar to this
   
   
6. When you have multiple orders do all your shipping assembly line style, print all your invoices at once (you can select multiple) and leave off the last page when you are hitting print (it is just tracking info), then print all your envelopes for sub $20s, then get out your bubble mailers for the $20+ and prepare to enter the info into either paypal or word.
   
   
7. Stop dropping your price by one cent to have the lowest listing. It drives me insane.
   

Thanks!
Like everything in my life, I get all the stuff from Amazon.
The bags:
https://www.amazon.com/gp/product/B071V7NCWV/ref=ppx_yo_dt_b_asin_title_o09_s00?ie=UTF8&psc=1

The backings are here:
https://www.amazon.com/gp/product/B0725XT5ZF/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1

I mostly use those to mail the stickers out, but I cut the down to size for the backings.

I would like to get some nice glossy backings made up at some point.

PMK sets hold their value quite well, you could get 80 for base set (97 msrp) (strangely, a set for $50 from 16 days ago hasn't sold or information hasn't updated). Pro mods probably 35 (52 msrp). Pro mods are harder to sell since only some people need them.

For shipping, use paypal ship now if you are shipping to conus from conus. Would recommend a cheap pack of small bubble mailers like this one or something from walmart.

Most people on here mail with PMs in a bubble mailer. I linked to it below.

As far as shipping goes, it would be more to ship to the U.S.(/u/gordie44 probably would be better than me to answer this), but I know there's a couple active silverbugs that are also from Canada, so international shipping might not be an issue.

Then the other highly recommended option is getting a tracking number on the shipment, but that can be something you and the buyer discuss

Some PC builders used to put large expanding-foam bags inside already built systems (with graphics card and cooler installed) which would fill all the spaces and prevent anything from moving. Supposedly it was very successful, or so I've heard.

Pull your GPU, use one of these. Took a 13 1/2 hour drive with this in the back of a u haul, because I didn't have anywhere else to put my PC. Worked absolutely perfectly.

These are the ones I bought - 10x13. I'm sure you can get anything similar and they'll work fine (read the reviews, if going with a different seller). I've been able to fit up to 3 or 4, depending on the shirt size. More than 2, though, and you're generally above the max USPS first class weight limit.

I use these guys and they're great!

Thanks again. Priority Mail sounds way too expensive -- another 33% of the $15 I'd charge. But $2.56 isn't so bad. So I just put it in an envelope (I have a ton of these), take it to the Post Office and say I want USPS Parcel Select? One thing I found said you can only buy that kind of shipping online.

I'm super late but they're just from amazon, out of stock right now though. Huns must've bought them all up

Then put that inside a priority envelope that's free at the post office

I've only had to spend about $3 to ship across the country (not counting envelope, but I bought a set of 100 mailers for like $8 on amazon so I don't have to purchase packaging anymore). Domestic should be about $6 with tracking/insurance. Canada, $10.

You should know better. The Frenchie polymailers are not from the Lularoe brand at all. They're purchased separately by Lula consultants.

A good cheap case is the large yellow padded envelopes.

Yep! I got these. I might end up buying some bubble wrap from walmart or something, though, since the protocol seems to baby the glass vials as much as possible.

Shopify is a good volume store.

Weebly is for small startups and mid-sized. Simply open an account, transfer your domain and done. You don't have to pay a monthly fee.
You'll have a branding on the bottom, but you can remove by buying Weebly Pro (which is cheap).

If you want Logos, designs or anything graphics on the cheap, check out Fiverr.com

For shipping materials, I suggest you use mailers.

To keep your shipping cost low, use USPS First Class Mail.

If you need to market, send small sized companies around you a sample and tell them you can supply it to them. I'm guessing an IT business will do well or even a gas stsation. You need wholesale pricing. This is where you'll make your money. Think of places that will buy in volume. A school, a community college, an office, maybe even a police station. Cal them. Send samples. You never know till you get your feet wet.

There is more to say but thats the gist of it.

You can also market with Google Ads, or Facebook Ads. It's up to you. You could also sell to

Here is what I do, and I ship things for very cheap.

When I get a bundle of free boxes, I will put aside a few to use as backers for first class packages. I divide up the box (usually the prefolded sides are finely sized for it) and cut them out. I will take the DVD, wrap in 2 layers of bubble wrap (not much) and place one of these sheets of cardboard on each side and tape them together. Then they go inside these cheap poly mailers.

I have sold hundreds of DVD sized items and never had one break this way.

I just started looking into flipping. I decided to do Amazon Trade-In for a couple of my old video games. When i send the package through UPS, can I pack it in a mailer envelope bag with bubble wrap or do I have to use a box?

amazon has some, https://www.amazon.com/EcoBox-Inches-Instapak-Temperature-2030-1/dp/B00KAFU0ZA/ref=sr_1_2?crid=U06Z7GFRFSMB&keywords=expanding%2Bfoam%2Bbag&qid=1555700280&s=gateway&sprefix=expanding%2Bfoa%2Caps%2C162&sr=8-2&th=1

100 padded mailers for $20.95 it's on my "Art Stuffs" list and it's been there over a YEAR!

I should not get this because then I would be able to send more random packages to people and that would cause me to just spend money on other people, and waste lot of time making special gifts and writing letters to people. And that might make the people who get the packages so excited when they open it that they might like, pass out and hit their head and go into a coma or something. And THAT is why I should not be allowed to EVER have those nice padded envelopes.

Plus I might spend so much time making crafts and gifts for others to fill the packages that I might lose myself in the crafting and forget my sadness and troubles and might actually get happy for a while. If I get happy tat might make the world totally implode. These bubble mailers may just be the most dangerous things to ever exist. And if I buy things to put in the mailers then I might end up not paying my bills and then I will end up with only the mailers to my name and I will have to build a house out of them, and clothes out of them, and then people might accidentally try to mail me and I would end up in some strange place only wearing bubble mailers.

It's not prime but it's free shipping. Does that count? I hope so because I have a really good reason that I should definitely not have those mailers. Also I hate writing letters and sending packages to people, and like making people handmade gifts is the worst. Those mailer would just lead to the misery of 100 people probably.

um no, i'm talking about these Poly Mailers you buy in bulk on Amazon. Poly is plastic. They were recommended by /u/FredWampy in his guide to selling on Amazon - on the sidebar.

http://www.amazon.com/gp/product/B000HG964S/ref=as_li_ss_tl?ie=UTF8&tag=ghg7584jr-20&linkCode=as2&camp=1789&creative=390957&creativeASIN=B000HG964S

If you can, you should ship it with only the case, PSU, SSD/HDDs, and motherboard with only CPU in inside the box the case came in.

The GPU and RAM are notorious for falling out and damaging the inside of the case during shipping. The CPU cooler can also break the motherboard during shipping.

Finally, a great step in protecting the parts is to use a expanding foam like this one too help keep the parts left in the PC from falling around. https://www.amazon.com/EcoBox-Inches-Instapak-Temperature-2030-1/dp/B00KAFU0ZA

I bought these (https://www.amazon.com/gp/product/B000HG9I5A/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1) for less than $10 with prime shipping. That's 100 bags! I fit 10 hats in each one when I was shipping for Hats for Sailors, and it cost about $4-6 to go from Pennsylvania to California. One hat should be closer to $2 or $3 depending on how far it's going. If you're worried about it getting wet, stick it in a ziploc before putting it in the bag.

Bubble Mailer. Amazon

Basically, envelope with with bubble wrap interior.

Note you don't even need a bubble mailer. We use these when shipping a shirt: http://www.amazon.com/gp/product/B000HG9I5A?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00

That will be $6 for my hard work and dedication

its not even like bubble loaders are expensive either

If you sell them I wouldn’t worry about boxes. They’re plush so I recommend these envelopes:

My bad. Copy and paste issues.

I use polymailers (I bought a stack of 100 a few years ago, still tons left - I think they're even cheaper on ebay). I have a kitchen scale that I use to weigh (include packaging), and then I just go through paypal's shipping service and put the weight from the scale plus one oz just in case of rounding error. Delivery confirmation is automatically added on, and then you can just dump it in any blue mailbox on the street.

International is different, though I still use the polymailer, I double up on it because customs is rough! If doing a mix, I'd still do the US ones at home and only go to the post office for international - it will be cheaper that way.

Make sure you only ever send to an authorized address. If you send to an unauthorized address on paypal, then you do not get seller protection and can be scammed. Along those same lines, I would caution sending a large amount of anything internationally if you are doing it through paypal - tracking can sometimes cost up to $30 and if you don't have tracking, you're not protected.
