Rollo,
The best person to answer that question is probably me, Yu Feng himself :>. The way it gets information from web sites is via a technology called web page scrapping. Basically the program sends HTTP request to amazon, retrieves the HTML page, parses the page just like parsing a XML document, then grabs the information you need, and send them back to client.
Because the code is proprietary, I can't share the code with you. But if you follow that logic you can pretty much code your own scrapping program.
Hope this helps.
