My order has been already placed but I would like to add one more item. Is this possible?

Due to technical reasons, we aren't able to make changes to your order once you've finalised it.

In case you notice that something is wrong or missing, you can cancel your order and reorder the items. But only as long as the items are still available. If they've sold out or the promotion's ended in the meantime, you can sadly no longer order them.
