If you go deep into all the settings you can turn all of amazons predictive jibber jabber off and turn off a ton of tracking. It has been awhile but I swear there were settings hidden everywhere. I just went back to amazon and it still seems to suggest some products based on what I just viewed so now I am wondering what the hell I even turned off.....it is actually fairly accurate now though (I looked at a timex watch and it is suggesting a very similar timex watch)

edit: My bad - it was just suggesting products I had recently previously viewed
