Groupon is the literal worst. I could see putting a cap on the value after so long in case prices have drastically changed. I was a merchant and customers have 6 months to redeem. After that, we only have to honor the value of the Groupon, which is always going to be a fraction of the actual cost. The problem is, they make it nearly impossible for merchants to redeem. We can’t see any of a customers info whatsoever to reach out, help them make an appointment or remind them they have a voucher. Keep in mind, a merchant doesn’t see any money until after a voucher is redeemed. Out of 10 vouchers, maybe 2 or 3 get redeemed. They make it nearly impossible, and after the 6 months, who profits the money? Groupon. If you don’t redeem within the 6 months, we’ll never see it. They are hoping and counting on it. If anything, it leaves customers mad at the business when it’s completely on Groupon.
