Yes, I've seen the ebay parser and the others but they just don't do all some of us really need. I am requesting someone who really understands eBay API to create a addon which actually turns any ebay link into an affiliated one, not "just items". This way, users can link to specials, stores, entire items page etc. Also, to have the "Geotargetting" option so that ebay links direct a user to the correct ebay page being either .com, .fr, ,uk etc.
I don't know much about ebay API but I know this can be done using the Advanced API. I know if this was made, there would be many happy users. I'd happily pay for it.
