Pre-Orders:  A pre-order is a reservation for a product that has been announced but not yet released.  Anticipated release dates and product specifications given are approximate and subject to change without notice.  You will not be billed for pre-orders until the item is released unless otherwise stated in the product description.  Our shopping cart assumes all items are in-stock and calculates shipping accordingly.  Orders that combine pre-orders and in-stock items may be subject to additional shipping charges.
