Here is a very interesting stat from a blog post about their motivation for doing personalized deals (http://groublogpon.com/cities/why-we-built-personalized-deal...):

"Over 35,000 merchants are queued to be featured on Groupon, and with 97% of our merchants wanting to be featured again".

That's an incredible number of merchants. I wonder how many of them would be willing to jump over to one of Groupon's many competitors?
