Good deal for people that use Living Social, personally I will never use them again. Worst customer service I have ever experienced. I have used them three times and it has been painful to get the deals to actually work. I will stick with Groupon.
All these group deal sites have to be taken wih a grain of salt. A lot of times the merchants are overloaded with business, and since their net profit is low on each voucher, they dont have quite as much inclination to provide good service. I've actually even been turned away from businesses when trying to use a voucher. They figure their net loss is so low, and they have so many people coming in, that it doesnt matter if they piss a few customers off.
When you wallow with pigs, expect to get dirty.
