It's National Pi Day, so treat yourself to some pie — pizza, dessert or both, whatever your heart desires! That first "Pi" isn't a typo and differs from the tasty "pie" we eat, though we could easily draw some geometric similarities between the two.

Here are some of the best Pi Day deals on pizza and pie. Royal Perks members who spend a minimum of $3.14 at Burger King on Pi Day can receive a free slice of Hershey’s Sundae Pie, per Burger King.
