Pi Day 2019: The best pizza and pie deals

March 14, otherwise known as Pi Day (because of the eponymous mathematical formula that begins with 3.14). What's so great about that? All you have to do is say it out loud and it becomes "Pie Day."

Hence an abundance of deals and promotions centered around pizzas and baked goods. Below I've rounded up some of my favorites, though this list is by no means complete. There may be local stores and restaurants offering discounts and giveaways as well, so check in with your local pizza joints, bakeries and the like.
