I'm what you call a Groupon junky. I buy A LOT of coupons and try out a variety of different business at a heavily discounted rate. I have to say that predominately my experiences have been very positive. The only negative experience that I had has been with one hair stylist (I don't remember the name) who simply refused to honour the coupon for a manicure that was included in the price so I was forced to get a refund. The refund process was painless, I email Groupon customer service and explained to them the situation and they immediately refunded the full amount on my credit card. It was as simple as that. More recently, I purchased a Groupon for fitness classes and I had a blast. For $20, I got 30 classes and an opportunity to try a bunch of studios using one pass. Thank you Groupon and MetaBody! I have tried out other deal sites and I have to say that I had problems with a few of them, because they don't properly screen their merchants and the refund process was none existent as they simply gave me the runaround until I threatened to contact my credit card company. Overall, I give Groupon 4 stars! I would have given it 5 stars, had it not been for that one experience I had with the hairdresser.
