We're working on making a hyper-local shopping deals/specials service that "just works." This service spawned out of our own desire for something better, and we have been developing and using it locally for a little more than a month. We're about to begin sending out private beta invites for several of the cities that we have been targeting.
I'd be happy to answer any additional questions at ryan@ayowe.com.
