I grew up in a household that celebrated math, attending college math classes throughout my childhood thanks to having a super enthusiastic math professor for a father. So Pi Day is a pretty fun day for the Gordon family. While we typically celebrate by trading bad math puns back and forth via text, we're not the only ones marking the holiday.
A number of retailers across the nation run special deals in honor of the numerical day, the bulk of which are for in-store purchases of, you guessed it—pies. Pizza and fruit pies are marked down to or discounted by $3.14 at the likes of Whole Foods, BoJangles, Marie Callender's, Hungry Howie's, and Your Pie. But if you're not about to wreck your diet for an arbitrary math holiday, there are plenty of online shopping deals you might want to know about too.
1. ThinkGeek is nerding out with 31.4% off 314 items
Leave it to the company that specializes in geeky products to have the biggest online sale for Pi Day. The niche retailer has discounted 314 different items, ranging from clothing and jewelry to home decor and toys, taking 31.4% off the list price of each. You can find things to reflect your love of math, science, Star Wars, Star Trek, Dr. Who, Pusheen the Cat, Marvel, Nintendo, and more. I may or may not have already ordered this math-themed shirt for my dad and this Star Wars necklace for myself.
2. eBay's got loads of items for $3.14, $31.40, and $314
