A pre-order is an order placed for an item which has not yet been released. The idea for pre-orders came when people found it hard to get popular items in stores due to their high demand. Shops like us then had the idea to allow customers to reserve their own personal copy. Pre-orders allow our consumers to guarantee immediate shipment on release, and our manufacturers can gauge how much demand there will be and hence the size of initial production runs. Additionally, pre-orders can take anywhere from 1-30 business days to be shipped. You can see on product pages where the "add to cart" button is replaced with a "pre order" button to let you know the difference. Please keep in mind that you will receive an email with all shipping details the moment your package is on it's way to you.
