Get Ready for Great Discounts and Deals for National Pi Day

Happy National Pi Day! March 14 is a time to celebrate the number, known as π, that represents the ratio of a circle's circumference to its diameter. Pi is also the first letter of the Greek word "perimetros," which loosely translates to circumference, according to PiDay.org.

The almost infinite number is usually rounded down to 3.14, making March 14 the perfect day to celebrate. Pi Day was first acknowledged in California in 1988 and in 2009 the U.S. House of Representatives named it a National Day. This acknowledgement has translated to great deals on actual pie, pizza pie, and other things associated with math, science, and food. Here are some great deals to explore:
