I really have a bad experienced with Groupon Everytime I used it. I have purchased an order of 300$. I didn't got to use it or redeem it. Some order got redeem but I've Never even used it. They will let you trade in, only with a certain time frame. If you pass the time frame, they won't let you trade-in. It's says "it's refunded" but Where did my money go? Well, I don't have it in my Groupon's account, not even a $1 back. OMG!
