I bought a coupon for a lunch place that I wanted to try. The restaurant was excellent, but this site's IT infrastructure prevented the merchant from honoring the coupon. This scam business actively chooses not to have a dial-in number for questions, and they will avoid your chats when you ask for live service. Fortunately, the restaurant itself accommodated me out of pity. I gave them a giant tip to compensate. You may not be so lucky. Buyer beware, stay far away!
