No, once you have placed an order and paid for it, including any shipping costs, you will receive your order without any additional charges.
Please note: if you use a “Pay later” service, such as Klarna, this service initially pays the amount to us on your behalf. The payment obligation then remains open in your Klarna account until you have settled it yourself.
If you do receive an email about an outstanding amount, always check whether the sender is legitimate before taking any action.
