Do you really believe that it is possible to generate an entire website with the API full of duplicate content from Amazon and outrank Amazon? I have yet to see a website that is doing this.
Then you haven't looked in the right places. There are several software packages you can buy that will have you setup and running in less than 30 minutes feeding your site with nothing but Amazon stuff. I've done it just to test it out and see what it does.
Most small affiliates don't have the know how to do the caching and in reality they dont' get enough traffic to even worry about it. An average affiliate on Amazon makes less than 50 bucks a month.
I predict, that they will soon change their TOS to dissallow all caching from their API.
