If you have cancelled your order and we have not yet started picking your order, you can make changes or delete your order. Unfortunately, we cannot increase the amount on a card payment/invoice and therefore cannot add products or change to a more expensive product. If we have already started picking your order, you can return the delivery to us when it has arrived at the agent or when it has been delivered to your home. Please note that you as the customer are then responsible for the return shipping back to us.
