I bought a warranty from Groupon, how do I redeem it?

Redeeming your Groupon voucher is easy. First, find your voucher number located under the barcode on your voucher. (You can access your voucher by visiting "My Vouchers" once you're in your Groupon account). Once you have your voucher number, visit https://www.cpscentral.com/groupon/. Enter your voucher number in the field and then the system should prompt you to register.
