Some good deals available; grant you that. Most deals for businesses you might not do business with otherwise; not so good. Discounts change frequently through sales and coupons but they manage to end up at about the same end cost (the deal is a marketing gimmick).
Customer service is a nightmare. Phone support is message saying go to our web site and help yourself. Link after link are dead ends, landing you at their first support page. Every phone number you find says they don't support phone support and go to their web page.
I have been charged twice for the same product on the same day on 2 different credit cards. You would think billing support would be readily available... NOT! Spend your time circling through their useless web pages. Even PayPal doesn't know how a customer can contact Groupon for a billing question or dispute. My time is much more valuable than what Groupon is saving in customer support costs. Done with them!
