I dispute this assertion or, in the very least, see this as being far more complex than you suggest, for two reasons:
1. Customers who might otherwise pay full price will end up using these deals, which is a direct loss to the business; and
2. The inventory may be used up by such offers to such an extent that customers who might otherwise pay full price may not be able to do so.

On this point you are I agree.
As for being "win win", apart from the above, you have to look at a number of factors:
- Do Groupon customers return?
- What word-of-mouth do they give to businesses as a result?
- How much do they spend (initially and on repeat visits)?
- Are they people brought in by Groupon representative of your existing or desired customer base? There is plenty of anecdotal evidence suggestings "Grouponers" are "cheap" (both in spending habits and tips).
The "offer marketplace" providers (Groupon, LivingSocial or whoever) seem to be missing a golden opportunity to mine useful data here by tying an offer redemption to an actual person.
