What does Preorder mean?

Pre-order refers to products, which are currently not in stock, but will be at a later time. 

It is possible to pre-order products that are not in stock. Pre-orders will be dispatched as soon as our warehouse receives new units. Customers will receive an e-mail with the order confirmation shortly before their order is handed over to the carrier. The amount will be deducted from their ccount immediately. We only dispatch paid orders paid in full.
