Okay! Here's my ideas for crowd-pleasers, that I think you can't go wrong with.. so you have to get 7 presents for £100, that's £14 each. Let's say you get them mostly off Amazon, so that you can get all of them shipped at once. However, I've suggested some gifts you could also get from shops around you, so that if you need to visit in person/avoid shopping, you could do that. Note however that it's free delivery week on Amazon right now so that should help.
