It seems Groupon is hot right now but I'm still not on the bandwagon. Most of the deals I see appear to be along the lines of "2 week membership to gym/yoga/karate for $X" or "Some tourist attraction for $X (normally $2X)" Basically, stuff where the vendor is trying to get your foot in the door or simply selling you an attraction where the "an $X value" may or may not be accurate. The helicopter one is interesting, particularly because this is something those 2,600 people would never search for in Google. But then end result shows that deals like this benefit Groupon much more than the vendor. If stuff like this keeps happening, are people going to want to continue offering deals on the site?
