they have different editions available - eBay, Amazon, CJ, etc. I use the commission junction edition. the purpose is to automatically display affiliate products when you enter your ID. they make it confusing for you. I'll show you a screenshot of it. https://www.diigo.com/item/image/1nqmj/d20v?size=o What would an advertiser's UPC or SKU be? also, lots of non-relevant crap has showed up when I just relied on key words. Something like this WOULD be a good way to automatically show relevant products from various networks on blogs, because this free edition doesn't cost anything and many of these products have a MONTHLY charge, which I'm not really open to for something like this. Working with data feeds sure is a hassle.
I am in the middle of knocking something up with that actually. Seems to work fine. I am using the ebay edition. Just sorting how to fetch the description but it basically just grabs auctions from ebay. Nothing vexing here really. Nigel
