Beware! Once they got your money - forget about it. Yeah, yeah - disclaimers etc.
But is it ridiculous to expect your money back, if the merchant have not provided what is promised?
That is what happened to me: I have purchased a gift certificate for my spouse. He contacted the merchant, who didn't answer the phone for days, then booked event, then cancelled it, booked another date, promising to call and never did.
I bought it to please my husband, and he was not pleased anymore.
I called LivingSocial for help, which they promised, but never did. Then wrote a letter asking for refund - well... read the first line.
Will never use this service again.
