If your Discount Code doesn't work, check whether the following applies to you:
✳ You input the wrong Discount Code.
✳ The Discount Code has already been claimed or used to the limit.
✳ You cannot use a Discount Code together with the installment payment method.
✳ You are not the owner of the code. Some codes can only be used by certain accounts.
✳ The product you are buying does not include in that code campaign.
