March 14th, 3/14/15, will be the only day we can experience a true Pi Day in our lifetimes, assuming the average life expectancy doesn’t double in the next few decades. To celebrate, you can specifically enjoy some pie at 9:26am (and 53 seconds!) or hound down savory and sweet pies alike all day long.

The latter is highly recommended.

Here are the current national pizza deals to appease your gluttony without hurting your wallet:

Blaze Pizza

This in-store promotion lowers the price of all personal pizzas to $3.14.

Domino’s Pizza

For $15.99, you can grab a large one-topping pizza from Domino’s along with eight pieces of boneless chicken that you should obviously put on the pizza. Just make sure you use code “9171” at checkout.

Papa John’s Pizza

Papa John’s is letting patrons take 25 percent off their regular menu items, provided that they use the clever code “25OFF.”

Papa Murphy’s Pizza

Feel free to use this coupon at a Papa Murphy’s Pizza, our other pizza dad, for a $5 large cheese, pepperoni or sausage pizza.

Pizza Hut

As a part of their Crust Flavor Challenge and happily coinciding with Pi Day, Pizza Hut is offering a large two-topping pizza at the price of $7.99. You just have to order online and try one of their new crust flavors.

Unfortunately, this deal is only available at select locations.

Please, please eat irresponsibly.
