I'd be interested to hear how the deals actually end up working out for the businesses in the long term. Sure, they get people in the door, but at a 50% discount plus the significant cut Groupon takes, they're not left with much. Plus it seems like most purchases are one off visits, as there are plenty of random acupuncture/restaurant/massage/etc deals to never have to repeat a place. Also, the collective buying power part doesn't really exist as far as I can tell -- I can't say I've seen any deals not get the minimum amount of buyers in the past year or so.
