yes there no problem there buddy , put adsense codes and you can affiliate for amazon percfect fines!
Yes I have actually viewed some sites that have both amazon and adsense. So there doesn't seem to be any problem.
My experience is that adsense click through on Amazon stores is very poor. I still use it some on my stores, I'm now trying ebay links to see how they do.
It can use at the same website but it is not good because I think Amazon-Aff is build more Income than GG-Adsense. (For My Website, Only)
You can do that, but be careful - your site will look much like an advertisement... you build trust with content and VERY FEW ads.
