I generally really dislike the Groupon approach and have since it started. The size of the discounts they enforce ensures a constant stream of people convinced they are getting a great deal without really mentally evaluating and doing due diligence on the offer: "Hey wow! 87% off?! This must be a great deal I shouldn't miss out on it!". On the flip side for most genuine honest businesses these levels of discounts are almost certainly a bad thing. They only consider them because of the promise of "more jam tomorrow" when the customers come back at full price. The problem being that they don't - they were only there for the deal price. This is the icing on the cake though. Whenever you create a new channel for selling products or services it won't be long before the scammers and conmen arrive in force to take advantage of it while they can.
