Any order with a pre-order item (look for pre-order in the product name) will be held until all items in that order are available for shipment. Once every item is available, your order will immediately ship.
If you would like to have the items in your order ship as they are available (instead of waiting on everything), please place a separate order for each. This properly accounts for the shipping expense.
You will be charged at the time any pre-order is placed, not when it ships.
Secure Pre-Orders however can not have contents of the order modified in whole or part once submitted, nor can the order be canceled, returned, or refunded.
