Some products are out of stock and backordered. In this case, the backordered items will ship as soon as they become available. If an item on your order is on backorder, you will be notified by e-mail within 24 hours. If the backordered item is part of a larger order and a significant part of the order is in stock then we will split the order, ship what we have and backorder the out of stock portion of your order. You will not be charged any additional shipping for split orders due to out of stocks or back orders. On international orders, we will hold your order until everything is in stock.
