BooksPrice Tracks Price Changes in Real Time

BooksPrice is a New York-based startup offering deal comparisons on books, games, DVDs, and CDs. Operating in the crowded online shopping space, it claims to reach an audience of 75,000 each month. A new service called RSS Price Watcher tracks price changes on sites like Amazon, Barnes and Noble, and Buy.com and notifies you of price changes via RSS. A similar feature can be found at RSStalker, which tracks Amazon price changes via RSS. This type of service is called persistent search since you get real-time updates in response to a single query.

Another interesting feature is their multiple book comparison feature. Like the slicker Ugenie, BooksPrice will search for the lowest total price for a basket of goods although it doesn't claim to try every combination.

Right now, Booksprice's major disadvantage is a somewhat unappealing user interface. There's a palpable difference when comparing it to Ugenie. I'd recommend a look at a Web 2.0 design guide.
