There is also a 2015 $1, and Blind Bargains has $1.

Oh, good idea! I thought $1 used to publish a gift guide, but either it's not out yet, or I was wrong, because I can't find it. Regardless, if you can get past how strangely the website is designed and laid out, they've got loads of interesting stuff, at reasonable prices. From clothing to gift-baskets to toys and games, they're worth a look.

Speaking of games, I've been lusting after a bunch of the stuff sold by $1 for ages, but haven't yet been able to justify it in the budget. They sell what seem to be some of the best kits to make mainstream board and card games accessible ever created. Dominion sounds like endless fun! And I already play Lost Cities on IOS and enjoy it, so I really wouldn't mind having a physical copy of that, either. Unfortunately, the kits to make the game accessible are $10 to $25, and then on top of that you have to purchase the game itself separately. So it's not exactly a stocking stuffer.

Edit to add: If you're in the US, you might consider $1 of DVDs with audio description. If the person you're purchasing for enjoys movies, getting them a DVD that includes audio description would be a thoughtful touch.
