When you purchase a pre-order, you are buying an out-of-stock or soon-to-be-available product not yet in inventory. We may collect no payment or a partial deposit at checkout, and store your payment method, then fulfill and charge the full or remaining payment at a future date. 
You can cancel a partially paid pre-order order that has not yet shipped and receive a refund according to our refund policy. If the order has shipped, then you can not cancel the order. See our returns policy for more details on returns and refunds.
