The second method of creating a comparison shopping engine is through the uploading of files called "data feeds"
The following description of data feeds is also taken from www.roboshopper.com
"Some comparison shopping engines use crawling for at least some of their results, but the difficulties with this method have led most of the established shopping engines to use the second method: "data feeds" from the merchant stores. Data feeds are basically special data files that the merchant prepares and makes available to the shopping engines.
The advantage of using data feeds is that all the information is provided in a nice format which is easy for the shopping engine to understand and analyze. It's much easier, faster and more reliable for the shopping engine to get its information from a data feed than by trying to crawl a merchant website."
