Livingsocial.com is one of the worst ways to discover a new business I am finding based on a few experiences. The businesses you get a coupon for always hate on the customers when they use the deal that they offered. However, it should be the businesses time to show off what a great business they are, but instead fail miserably by hating on customers using coupons that they themselves offer up. If you don't like customers using them, don't offer them. Poor experiences with the businesses makes you not want to go back.
Also, they have fine print that is very misleading and conflicting. In one area it says that the "Paid Value Does Not Expire", however, they say in the Fine Print it says " voucher subject to forfeiture".
