So after a little research (read: Google), I am posting what I think is a pretty comprehensive list of group buying sites. Not all are fully operational, and of those that are operational, not all offer deals for every city. The market it seems, is much bigger than I supposed. I wonder if all of them are breaking even. Theoretically, there are enough businesses in each city that each of these sites should thrive if they can convince enough of the business to offer discounts.
So far it seems the best deals are coming from Zappon, Wicount, Vuvuplaza and Twangoo, but take a look and judge for yourselves.
