In short, it is not possible to cancel or edit an order once it has been placed and paid for.
However, there might be instances where it is still possible for us to keep the order from reaching the next step which would allow us to make some changes in the items ordered. For this, please be so kind as to contact our Support Team as soon as possible after placing the order. Make sure to do so under the same email address that the order was placed with:
