Terrible business model
Groupon might have made its founders (long gone) a fortune but the business was unsustainable. They hyper inflated into new territories screwing businesses left and right and leaving a barren wasteland of broken / burnt businesses behind them.
These days Groupon mostly sells crappy service deals - manicures, carpet cleaning etc. - where the business has low overheads and artificially inflates prices for a service to make the discount seem like a good deal. Not only that but there are dozens of rival coupon services selling similar deals. I'm surprised they've lasted as long as they have without imploding.
Biting the hand that feeds IT
