To preorder an item, simply add it to your basket as you would with a regular item. In the checkout, you have the possibility to choose between combined or split delivery, if you also have regular items in your shopping cart.
Please note, that once you have placed and confirmed your order, it is not possible to change anything about it, including the delivery option.
The estimated delivery time can found on the product page and in your order confirmation. If the preordered items are delayed, you will be informed about it by email and the payment reservation will automatically be extended.
