Pi Day Deals and Specials for March 14, 2020

Pi Day (named after mathematical constant pi which starts with 3.14) is coming up this Saturday, March 14, 2020, and a number of chains will be slinging pizza or pies at a discount to help celebrate the day (because pizzas and pies are usually circular and pi is the ratio of a circle's circumference to its diameter).

So without further ado, here are some Pi Day deals and specials for March 14, 2020:

- 7-Eleven - On March 14, 2020, you can get a whole pizza for $3.14 in-store through the 7Rewards app or delivered through their 7NOW app at participating locations (limit one discounted pizza).

7Rewards members who visit a participating 7-Eleven store on Pi Day can also buy a pizza slice for 50 cents (limit one per customer).

- Blaze Pizza - They'll have a deal for good for a $3.14 pizza on their mobile app that's available to redeem after 3:14 PM on March 14, 2020 only.

If you haven't already, you'll need to download and set up an account on the Blaze Pizza app by 11:59 PM PST on Sunday, March 15 in order to automatically receive the new Pi Day reward.
