I couldn't figure out how to add adsense to my new Amazon page or whether it is alright (without violating adsense TOS) or even it is possible. What I would like is to have adsense on the sidebar below the categories module. Please check this http://weightloss.healthgenie.org/Stores.htm
Yes, you can. Log in to your adsense account. Click the tab at the top that says adsense setup. Google will walk you through the steps.
Just log in to your adsense account and get the code, copy the copy and paste on your sidebar. That's all
