Maybe it's just that the website is two sentences so I don't see the use of the product. Do you plan on displaying the information by users and making a social network out of it? Do you plan on monetizing it? Was this just an application you made while learning to program Java and wanted to show off your accomplishment?

The hardest part as always will be adoption. This will only be useful to me if there is a critical mass of users to supply me with feedback and make me want to leave my own. Figure that out (incentives? Coupons? Humor? Maybe add a lowest local price search function?) and maybe you'll be on to something.
basically, the way to think about mvp's, is it's the "done is better than perfect" equivalent of a proof of concept. Whereas in the old days, someone would innovate and then put out a proof of concept, these days we skip the innovation stage and put out a proof of...ability to put a database app together? I dunno exactly. Sorry about the snarkiness here, I just think there is life outside of this particular bubble.
