Deal-scouring isn't a new idea by any means. Nonetheless, I've been playing around with it, and I'm very much impressed with the speed and ease of use of the service. Well done.

One suggestion though that may or may not be helpful at this point. Perhaps when a user searches, you can have a "short list" that lists the most popular products in that search, so that the search can be narrowed to a single product.

For instance, when I type "bluetooth headset," a short list of headset models could come up on top of the results. When I click on one, it limits it to, say, H700.

Also, I searched for "Playstation 3." I was looking for the console, but got one console result and a bunch of games. Perhaps categories like "Playstation 3 Console," "Playstation 3 Games," "Playstation 3 Accessories," etc.

The former would be much easier to do than the latter I'd imagine, but both types would be helpful.
