There are other reasons to need gifts. Birthdays, special events, or just the need to have something nice. I frequently lay in presents against the rest of the year, sacrificing storage space for the sake of savings. Or maybe I get myself a nice thing, because it's nice to have nice things. I try not to practice too much retail therapy. That doesn't mean I don't occasionally treat myself.
May I present the Unicorn Empire holiday sales?
Unicorn Empire Designs is an artist-owned shirt and print design shop belonging to the fabulous Amber Whitney, who has designed some of my favorite shirts (I'm wearing my Steven Universe shirt right now, and seriously considering ordering myself a second "We Are Not Things" tank, because I wear it so damn much that why not?). If you're one of the lucky ones who got a Sparrow Hill Road shirt, she did that design.
It's too late to order from her for holiday delivery, especially if you're not in the US, but her holiday sales are still ongoing. You can get some incredible fannish gift sets, and better yet, free shipping on any orders of $75 or more. Check out her stuff, and see if some of it needs to come home with you.
More seriously: Amber is an independent artist who does incredible things. So incredible that the art theft has, naturally, gotten more and more common as other people went "oh, it's just fan art" and tried to profit off it without compensating her. So if you've been considering a shirt, consider it now, and help give her the happy holiday that assholes attempted to steal away.
