If you are one of those people, you need to know about free shipping day. On December 17th, more than 1,000 merchants will offer free shipping on orders purchased that day. Apparently they promise to get your order delivered by Christmas Eve if you live in continental US. Go ahead and check out the list of merchants to see if any of your favorites are participating!
