may have discovered a route around the $30 minimum purchase requirements-
you'll notice the coupon only works for purchases of $30 or more, however, if you fill your shopping basket with several titles, and proceed to the final order screen (after you have submitted your order with shipping choice and coupon code), it will give you a last chance to remove items and check your order on the same screen that it tabulates taxing and total purchase order costs. I removed the extra items, which brought the cost below the $30 minimum, and submited the order. It went through fine, and i recieved a reciept. Unless orders are checked individually, I see no reason this order shouldn't ship and be billed at the lower balance.
