Living Social does not honour their offer of "recommend link and if 3 people buy you get yours for free". I did this for a photography course, sent the link to 3 friends. 1 friend did not have a credit card so I used the same link that I sent him and paid for his ticket. I got a email from Living Social saying "Congratulations, I get mine ticket for free". My credit card never got refunded. I followed up and was told because I had paid for my ticket and my friends ticket with the same credit card the offer did not apply. I got a really "we don't care" attitude and they palmed me off.
