Is there any other such as http://www.datafeedfile.com that gives excellent product price compare such as http://www.datafeedfile.com/examples/javascript.php?eid=0_4 What script uses this site - http://www.epinions.com/prices/Samsung_LN_22A650_LCD_TV or http://shopper.cnet.com/flat-panel-tvs/sony-bravia-kdl-52xbr6/4014-6482_9-33060608.html?tag=mncol Thanks, mojtata
these types of sites are specially designed with a module to grab the prices of different sites by using the scriptings and API's of those sites like for amazon/ebay any one can use their API's to search the product price of any product and then display it to any other site!!! I hope you got the understandings of these price comparison type sites which actually do the work of price grabbing from different sources...
The closest script like those that is available for purchase that is anywhere near affordable is probably kaonsoftwares.com
