The user follows a directory tree, ending with a search of the desired product category. Pricescan returns a list of competing products, each with a best price . Selecting a product then gives a long list of vendors, in order of increasing price. This service is unique because it includes not only web-based vendors, but many traditional vendors as well. This easy to use guide offers probably the widest range of goods, and excellent search options, including the ability to search auctions.
Detailed information is returned, including how many items each vendor has in-stock .
However, I question the independence of the service, and the prices seemed higher than with other services. This is another guide, compiled from outside databases supplied by vendors. It is relatively easy to use, but favors partner vendors. Each of these bots weaknesses were more noticeable than their strengths. Many of them actually return the same results.
