Online - Go the Rewards widget on the bottom right corner of any page, then go to Redeem Stars. Click the reward you'd like, and a redemption code will be automatically generated for you. Enter this code as a coupon in the check-out page.
WARNING: Once you redeem a reward, the associated stars will instantly be removed from your star balance and cannot be refunded. However, once generated, codes do not have to be redeemed immediately. Codes will be stored in your account until used and never expire.
In Person/Conventions - Please ask a staff member to assist you through the check-out process.
