 What is backorder?

Backorder is any item that is temporarily out of stock. Products are usually in stock and can be shipped immediately. However, if we are unable to ship your order immediately, and the manufacturer is unable to ship directly to you, we will immediately email you of any delays and make our best estimate of when the item will be ready to ship.
