"This Web Service can be used to get the Sales Rank and/or price for any book available on Amazon and/or B and N Web sites."
I’ve been trying to explain to some people at Amazon that they should turn their associate program into a service, but it’s been tough to get the message through so far. So PerfectXML is doing it for them. I guess they do the screen scraping for you and expose the results in a clean, workable way.
Message to people in charge of affiliate programs: they’re about distribution and the extended enterprise, not advertising (CJ, can you heaar me?) Get over banners and open your sites through smart urls and/or web services.
