I and many others would greatly appreciate the ability to track DVDs and Blu-Ray Prices

PriceCharting is a fantastic website for tracking all sorts of collectibles, but there is no feature for tracking the value of Blu-Rays and DVDs. While they may not seem valuable initially, once you get into anime DVDs and Blu-Rays they are highly collectible. Currently, there is no app or website that offers the ability to track the value of a Blu-Ray and DVD collection based on eBay sold listings. The apps that are available are either highly inaccurate, (like IcollectMovies) or they don't list the total value of one's collection (like My Movies from Blu-Ray.com). It would be a massive service to DVD/Blu-Ray collectors everywhere.
