Dec. 2014, purchased 4 tickets to "Paint Nite" for $24.74 each good for 1 class normally $45.intended to use for next year holidays. Verified expiration was 12 months. I tried to redeem one in Oct. 2015, but was asked to pay another $20, or full price for the class ($45). They claimed the coupons expired. The same deal was still running. I contacted Groupon several times and got the runaround. I did not ask for a refund, just a credit so I could repurchase. They would not credit and "Paint Nite" still wants me to pay $45 per class. No customer service and rip off to get you to pay full price. I'll never use these.
