Plenty of unofficial holidays exist purely because of how a particular date looks—we’re looking at you, Mario Day—but among these, Pi Day might be the most iconic. Every year on March 14, math nerds everywhere celebrate pi (π), the ratio that defines the circumference of a circle to its diameter and an irrational number that happens to round to 3.14. Even if you’re not a huge fan of pi (maybe it just gives you flashbacks to high-school geometry), you should know that ThinkGeek is running a major sale for Pi Day—everything on the site is 31.4% off for today only. All you have to do is use the promo code PIDAY19. Only pre-order items are excluded. The sale ends tonight at 8:59 PM PST / 11:59 PM EST.
ThinkGeek positions itself as the go-to destination for collectibles and licensed merchandise around gaming and geek culture, and its range of offerings is expansive. From Rick and Morty action figures and a Legend of Zelda ocarina to a Captain American shield doormat and a giant Snorlax bean bag chair, ThinkGeek has unique offerings for practically every fandom under the sun. You’ll stumble across random, wonderful things you never knew you needed, like this glowing Pac-Man lamp that plays Pac-Man music when you plug it in, or Jon Snow’s direwolf, Ghost, in plush form. If you’re planning an upcoming cosplay, you might just find the accessory you need. And it’s all on sale, so now’s the time if you’ve been eyeing any kind of merch, wishing it were cheaper.
The size of ThinkGeek’s inventory can be overwhelming, so to make things easier, you can shop by interest, including specific video games or brands like Zelda, Dragon Age, Pokemon, and Fortnite. You can also shop within product categories, so if you’re looking for something specific like board games or desk decor, it’s super easy to find what you need.
