LivingSocial Deals --

I saw this on Facebook. Has anyone investigated this in the Hill Country? Costs -- do they offer anything useful? I did surveys connected to E-rewards thinking I could get the equivalent of Amazon points, but it's pretty much useless -- I have $50 earned and they want me to get things like 15% off 100 dollars at Nordstrom's. Since I am not spending unless I have to ($~$600 for battery, master cylinder, jump (not) and cat meds yesterday) where's my 15% off there?!
