It took some server-side coding, but I have a nifty deals page up and running. The deals page is as current as the feed it scarfs (read every half hour).
Lacking user-interface polish perhaps, but it is space-efficient and free of distracting gunk, and thus an effective tool that makes it easy to pick out deals by percent discount, brand, or category. Use the filtering provided and/or use the command in the web browser to search.
Give it a try, bookmark it in your web browser, and thank you for buying using the links from that page or any B&H link on this site, so I get credit over at B&H Photo.
