Pi Day is almost here!
Celebrating on Friday, March 12th? At this point we recommend paying extra for Express Mail shipping.
Celebrating on Sunday, March 14th? Try to order by mid-day Wednesday, March 10th for delivery on or before the 13th . Orders placed by mid-day Thursday still have a good chance of arriving on the 13th. We also offer overnight shipping to most US zip codes.
This deadline is based on USPS guidelines and our experience. Priority Mail orders placed by this deadline are very likely to arrive on time, but are not guaranteed to do so.
