The $300 deposit reserves this wheel/tire for you once they do return to stock. As soon as we have the wheel/tire in house we will invoice you for the remaining balance. Simply pay the balance and we will get your order headed your way! Should you decide to cancel, before we have all pieces of your order, we will refund the $300 in full. If your order is in house and you still request to cancel, even though we are prepared to ship, there may be shipping/handling costs passed on to you, never to exceed the $300 down. We always do our best to get the package you want as quickly as we can and our deposit program is VERY popular with our customers!
