What is the 'Backorders' section?

The' Backorders' section is very similar to 'Order History' section except it only shows details of your backorders (if you order an item that is currently out of stock it will be placed on backorder for you and shipped to you as soon as we have it available again). Once a backorder has been completed (you have received the goods) the details will be moved to the 'Order History' section.
