Everyone has their own view of what is unneeded on Amazon's incredibly cluttered pages. This is mine. It removes features I don't want, which includes making the purchase options area much simpler. Each removal is clearly marked in the code if you'd like to take some out.

This is very similar to http://freestyler.ws/style/13231/amazon-us-with-less-clutter, if you'd like another option that removes a different set of elements.
