Reddit mentions of Flip Top Stopper: Creates Airtight Seal, 3-Pack

ShipCider.com has a great selection and reasonable prices (before shipping), if you know what their tastes are (at least dry vs. sweet). If you decide to go that route, and know a bit of their likes & dislikes, I'd be happy to suggest some (I'm familiar with most of their inventory as I live in Seattle and they ship from Portland). I'd make sure its not something they can get locally if you're going to pay for shipping though.

Some cider clubs are trying to start up, but currently I believe they are only offered by individual cideries, so like winery clubs and such, I think are only a good option if someone likes everything a cidery makes.

Some nice glasses and expanding bottle stoppers is another more general option too (tulip shaped glasses are popular, but I'm partial to brandy snifters).

Something like these for stoppers works on most bottles:

These are some nice looking glasses (by comparison, I like the brandy snifters I got for $4 each at Cost Plus World Market):
