PRE ORDER stamps count toward FREEE SHIPPING with orders totaling $48.00, but should be ordered seperately from other stamps unless you don't mind waiting for the order to complete. In other words, free shipping applies to each individual order ! AFTER PLACING ORDER YOU MAY PAY WITH EITHER A CREDIT CARD OR USE PAYPAL. IMPORTANT! Credit Card information is taken on the next screen. Select "don't have a paypal account" in order to enter your credit card information.
