From TFA: 'a [GroupOn] spokesperson said it was "difficult to give an accurate figure" for how many businesses are repeat users of the site.'

Really? I would have thought it would be pretty easy to run a query on their accounts and find out a nearly exact number.

I think it's one of these situations where it's not difficult to calculate, but it's difficult for them to release the figure. I suspect it would clearly indicate the malcontent of small businesses. "0.5% are repeat users" doesn't really bode well for you if your company is looking at an IPO.
