http://biggestpricedrop.com http://biggestpricedrop.com I created the site because I've always wanted to sort through products by how much they've dropped in price (in like the last day or two)... Does anyone know if another site like this exists? I think it's unique because it tracks the deltas of prices. Useful if you want to know what just went on sale. Currently, I get the prices from feeds from the stores but I am working on a scraper to get even faster updates and better in/out of stock data. Is there perhaps another niche where my tool can be used? Real estate? Technology goods (like bensbargains.net? Thanks, any suggestions/feedback would be greatly appreciated! david
