Placing an order for an item that is temporarily out of stock is called "backordering". When you place an item on backorder we will ship the item to you via standard shipping as soon as it becomes available (domestic orders only). You are never charged for a back-ordered item until it is shipped, and you may cancel an item on backorder at any time. You do not pay additional shipping for backorders.
For international orders, we can only ship one package per international order. If your order consists of several items, one or more of which are on backorder, we cannot ship the in-stock items until the backordered items become available. If you want to receive your in-stock items right away, you must remove the backordered items from your order and re-order them when they are in stock or place the backordered items on a separate order.
