7 Deals You Can Only Get on Pi Day

Find out what deals you can score on this day that celebrates the mathematical constant.

Pi Day is almost here! What’s that you ask? Why, it’s the global celebration of the mathematical constant, pi. Because the first three digits of pi are 3, 1 and 4, it is observed on March 14 (aka 3.14). Some businesses—especially those that are somehow connected to the “pie” theme, such as pizzerias and bakeries—often run special promotions to mark the occasion.

“As food holidays become increasingly popular every year, more retailers, brands, and restaurants are starting to participate,” says Sara Skirboll, shopping and trends expert at The Real Deal blog. And that includes Pi Day.

While only a limited number of Pi Day deals have been announced already, you’ll likely hear more about it as the day approaches. “While brands have kept quiet so far about their specific offers, based on past year deals we can expect to see great offers from restaurants like Domino’s, Papa John’s, California Pizza Kitchen, and more,” says Skirboll.

Search for Pi Day hashtags and mentions on social media to stay in the loop on the latest deals, and keep checking the Pi Day website. Find out how apple pie became America’s favorite.
