I doubt very much that Groupon has that kind of moolah to be throwing around :) Let's just leave it at that.
(In my original comment, I considered including that the biggest risk to the business plan is Groupon, and that therefore the business plan should include hedging or insuring against non-payment for groupon reasons. But thought that was too mean-spirited and negative; I hope groupon does well sustainably and indefinitely - by helping small businesses, not at their expense.)
