Also, I had no idea what the site was about at first. I had to actually search the site a bit to even figure out what was happening.
In regards to the idea, I think it is a decent idea, but this seems like a feature that may be best featured within another web application. After this is perfected, I can see the potential for a company purchasing it if only for integration within their own products; however, it does not seem like it has much potential value until you add a bit more to it. It needs to be tweaked slightly. I would continue focusing on the core concept just a tad longer before moving on to additional features.
We also added some intro words up top.
We have a pretty easy to use API that might be integrated with Centrl/Loopt/etc at some point in the future. But, I'd argue that the fact that retailmenot/slickdeals/fatwallet/etc are independent sites validates the 'deal finding' model and suggest we could surive individually as a niche site.
