HURRY! This is an awesome freebie! From what I can tell their are no strings attached. You have to place your order online and the only thing in your cart can be this poster. I found this through Freefly this morning. You simply print out the coupon for a free poster from Walmart and take it with you when you pick your poster! SWEET! Print your coupon here.
(NOTE: If you are new to Freefly you will be asked to sign up for a free account. If not you will be redirected straight to the coupon!)
