Hi Berk, A really good standard to look at has been developed by the University of Manheim and is shopinfo. With some simple scripts, you can download and get everything across a large number of vendors. What is actually done is that a csv file holds the actual prices, you get the xml file which tells you then how to decode the data. I have some perl scripts that I could publish that will automatically download about 8 million items from a range of websites across Europe. It is all fascinating stuff.... Let me know if you are interested and I will publish the links..
