I gave up on Amazon about a year ago. Once their aff program turned into an attempt for free advertising on my sites
. I got better things to do then trying to promote an aff program that pays 36 cents per month (with more than 2000 clicks per month from my site…..yeah right
). I replaced amazon by ClickBank products. Much better commission rates and much better converting products. I’m using an auto product feed (Adsense type of thing ) to my pages and it works excellent so far. Check it out here
