Pi Day 2016!

Pi Day (March 14) is one of our favorite unofficial holidays around here, so naturally we decided to celebrate with a sale on all of our Pi-themed products! 
Just use the code PiForAll and get 20% off everything in our Pi Day 2014 collection through March 16, 2014. Why 20% off? Sometimes it's good to have a nice round number for a change...
And don't forget about our free shipping to anywhere in the U.S. on orders of $75 or more!
