Do you know of a search engine for products?

A new product search engine has been conceived recently. There is this new search engine that has come about that has a few million products listed on it and they all have their descriptions and the prices given too. There are hundred thousands of categories and these categories can be screened to search for the listed product. Each and every web shop has several categories in which the products have been listed and inside the web shop where the products are listed, you can search for what you need too. Depending on the price, sort results, easy to use interface and simple functions, you can make the search. Any comments?
