We sometimes allow backorders for an item that is out of stock but is expected to be back in stock. Just look for the Backorder button where you normally see Add To Cart. You will not be charged until the item is in stock and your backorder becomes a sales order.
Important Information:
On the other hand, if you order an item which is in stock on our website, but we learn that it’s out of stock when we process your order, the item will be removed and refunded so that the rest of your order can ship. If it’s the only item on your order, the order will be canceled.
