Maybe I'm cynical, but I think they are trying to grab a ton of money while the getting is good, knowing that their business model is not sustainable. They spend enormous sums of money on sales-staff (to get the deals from vendors) and many vendors say they are unhappy after the groupon goes live. Apparently most groupon-buyers are cheap one-time-visitors and the local vendor doesn't recoup their expenses.
