When you place an order for a Pre-order item, we will send an authorization hold request to your card issuer. The authorization hold is not an actual charge and will eventually expire and drop off your account based upon the time-frame set by your card-issuing bank. If the authorization hold expires before the item’s release date or before the order is ready to be shipped, the authorization will automatically renew. If any attempt to renew the authorization fails, you’ll be reminded by email to change the payment card type/details. You won’t be charged for your order until it ships.
