Here are 10 places to enjoy free pie and cheap pizza on National Pi Day 2020

Whether you’re great at solving math problems or just love food freebies (who doesn’t?), National Pi Day is an occasion to be celebrated — and it’s just around the corner.

For those who need a refresher, pi is the never-ending mathematical constant beginning with three digits (3.14) and is represented by the Greek symbol “π.” The day was officially recognized by the U.S. House of Representatives in 2009, but even before that, it’s been a popular day for celebrating round foods.

Many restaurants, both local and national, that sell pizza pies or regular sweet ones take advantage of the day to give customers a slice of the good stuff at a better price. Here’s a list of places partying for pi on March 14.

Blaze Pizza

This customizable pizza joint is offering pies for, you guessed it, $3.14! To get this deal, download the Blaze Pizza app before March 14. Plus, if you use the Pi Day reward in the app, you’ll get $3.14 off a large sharable pizza valid March 15 through 31.

Coco’s

This casual restaurant chain with a hefty bakery will dole out slices of pie free of charge between 4 p.m. and 10 p.m. on March 14. To enjoy a slice, just be sure to become an e-club member first by signing up on the restaurant’s website.
