Your Pie hosted its fourth-annual Pi(e) Day event on March 14, 2013. The event celebrates pi, the ratio of a circle’s circumference to its diameter, approximately equal to 3.14 (thus why it takes place on 3/14).

In celebration of the mathematical symbol that gives pizza its shape, Your Pie offered their craft ‘pi(e)s’ for $3.14. “The promotion is our way of showing appreciation for our customers in a fun way,” says Your Pie founder Drew French. “The first Pi(e) Day event was so successful that we just had to keep it going.”

Pi(e) Day will took place at all 16 Your Pie locations across the Southeast. While pizzas carried a base price of $3.14 and include an assortment of fresh ingredients, additional premium ingredients or gluten-free dough cost extra.
