Within 3 days of delivery, you may return any certificate for a full refund as long as none of the rounds have been used. We cannot give refunds for any certificates that have been used or partially used.
Once the certificates are in your possession, they are your responsibility. If you do not use the certificate before the expiration date, we cannot replace it. Just like a ticket to a football game, if you miss the game, you do not get to go to another game just because you missed the game you had a ticket for.
