take on the Groupon deal

I read an article today about a cupcake shop across the pond who was basically put out of business because of a Groupon deal they had advertised when 8500 people showed up demanding a dozen cupcakes at a 75% discount.  

I get this new concept and we have participated in a couple of these things but I find that the vast majority to Groupons, living social buys and the one from Amazon we buy are an almost complete waste.    I walk into a take-out restaurant the other day with a $30 Groupon but was informed I had to use the entire amount in one sitting or the balance on the account would get cancelled.   You can't possibly buy $30 worth of food in one of these places even if you order two extra smoothies, a second bag of fries and three bottles of overpriced water.   

But that's not the worst of it, I find that ever deal I have ever bought was one of those  'yeah I've been meaning to get back into shape' moments as I signed up for 10 classes of boot-camp for $50.   Problem is that I'm now getting daily reminders that my Groupon is about to expire and I have about as much interest in Boot Camp as I would in eating 102,000 cupcakes..
