National Pi Day 2026 Deals: Pizza Chains Offer $3.14 Specials, BOGO Offers and More

National Pi Day on March 14, 2026, brought a wave of promotions from pizza chains and other eateries, with deals centered on $3.14 prices, buy-one-get-one offers and discounted pies to celebrate the mathematical constant 3.14.

The unofficial holiday, honoring the ratio of a circle's circumference to its diameter, has evolved into a major food event, particularly for pizza — a circular favorite. Chains nationwide rolled out specials Saturday, many requiring app downloads, loyalty sign-ups or in-store visits at participating locations.

Pizza Hut led with multiple offers. Customers could buy one medium or large "Create Your Own" pizza and get another free, available through DoorDash and in-store while supplies lasted. Separately, Pizza Hut promoted a $10 large three-topping pizza on choices like the new Hand-Tossed, Tavern Style or Thin 'N Crispy crusts for carryout or delivery at select spots.

Blaze Pizza offered a standout buy-one-get-one deal: purchase one 11-inch pizza and get a second of equal or lesser value for $3.14 in-store on March 14. App users received a digital code for a separate BOGO Simple Pie cheese pizza redeemable from March 14 through April 6. DoorDash amplified the promotion with a free 11-inch cheese pizza when buying one through the app during the extended period.

Papa Johns provided rewards members a BOGO-style offer: buy one large or extra-large pizza at regular price and get another for $3.14 on Pi Day. Members also gained access to exclusive deals through March 20. Other ongoing specials included Papa Pairings at $6.99 each for two or more items and large one-topping carryout for $7.99.

Domino's highlighted its "best deal ever" with any pizza up to seven toppings for $9.99, plus select items at $6.99 each when buying two. The chain's promotions focused on value rather than direct $3.14 ties but aligned with the holiday spirit.

7-Eleven and Speedway gave 7Rewards and Speedy Rewards members whole pizzas for $3.14 in stores or via the 7NOW Delivery app. Speedy Café locations offered large one-topping pizzas with customizable toppings and three-cheese blend for the same price.

Marco's Pizza let customers buy any large or extra-large pizza and add a medium one-topping for $3.14 using code PIDAY online or in-phone orders.

Mountain Mike's Pizza rewarded Mountain Rewards members: purchase any medium pizza and get a second one-topping medium for $3.14.

Other participants included Uno Pizzeria & Grill with a second pizza of equal or lesser value for $3.14 on regular-priced deep dish or thin crust (use code BOGO314 online), &pizza with additional pies for $3.14 using code PIDAY, and Papa Murphy's with 31.4% off regular-priced items via code PIDAY26 online or in-app.

Sweet treats rounded out celebrations. Burger King gave Royal Perks members a free Hershey's Sundae Pie or Cinnamon Apple Pie with any $3.14 purchase. Some chains offered pie discounts, though pizza dominated.

Deals varied by location and often required loyalty enrollment or apps. Chains urged checking websites or apps for availability, as promotions were while supplies lasted and excluded some items.

Pi Day, recognized by Congress in 2009, blends math appreciation with fun food promotions. This year's offers reflected growing participation, with delivery platforms like DoorDash aggregating chain specials for convenience.

As March 14 passed, many extended deals lingered into April, giving latecomers chances to save. The day proved a win for pizza lovers seeking affordable slices in honor of an irrational number.
