Unfortunately, we do not have a way of tracking when a voucher has been used. In order to find your purchase's redemption status, you'll need to contact the merchant directly. They will have records of which vouchers have been already used.

In the future, be sure to visit the "My Account" section of Tippr after you've successfully redeemed a voucher. Here you'll find an option to "Mark Voucher as Used." If you ever click this by accident, simply click "Mark as Unused."
