98$ spent for a "deal".
When i wanted to take an appointment with the society of the so-called offer, i never had any answer, whereas i sent them emails and phone calls.
I came directly to the society, someone told me they were not here anymore, but was unable to tell me if they just had moved or if they didn't exist anymore.
Now Groupon don't want to refund me.
Really bad experience... Groupon = zero, finally as their offers. I'll remind that for the next time.
