Interesting spin on Groupon deals, but for online products. Seems very well polished for an MVP, and many people may find this a directly useful way to encourage people to spread awareness on Facebook. The HN discussion is here.
One thing that's missing is, probably, the central "tell me about the daily deals" aspect which actually draws users into Groupon (and made Groupon the success that it is). But that might come later. Or, if you want it right now, AppSumo is the closest approximation available at the moment.
