All tournaments awarding coupons will automatically enter you into the next available tournament providing that the tournament is still in registration or late registration. If the tournament has not yet started you can go to its lobby and de-register and the coupon will remain in your account for use at a later time. However, if you are automatically entered during late registration there is no possibility to de-register and you will have to play.

The see your unused coupons click on Games on the menu bar at the very top of the lobby screen and select Tournament Coupons.
