The Gift Vouchers can only be canceled by the buyer within 1 hour after the purchase and will only be valid after the reception of the confirmation email. The undesired Gift Vouchers can not be returned and the discount codes can not be used to purchase another Gift Voucher.
If the value of the products added to the card sum less than the value of the Gift Voucher, the remaining value will continue in the plafond of the code to be used in the next purchase. If the purchased articles exceed the value of the Gift Voucher, the remaining value must be paid by credit card to complete the purchase.
The purchased products with Gift Voucher can be returned for exchange, but can not be reimbursed. Only the additional money paid aside the Gift Voucher will be reimbursed or a new discount code will be issued.
