After you have paid for the order, it is no longer possible to add additional items or change an item.

You can always place a new order, but then you pay shipping costs for the new order as well.

Otherwise, you can cancel your order:

• If it is not paid for yet, you can do it yourself
• If it is paid or payment is on its way, contact customer support. We can then cancel and refund your order, or start a return procedure.
