$3.14 Pizzas and Other Deals You Can Snag on Pi Day

This Tuesday is Pi Day—March 14, or 3.14—an altogether awesome day if you love math or, more likely, discounts on pizza and pie.

Pi Day is a celebration of the mathematical constant π, the ratio of a circle's circumference to its diameter, which starts with 3.14 and goes on endlessly.
