This website is not a parody, and fair use does NOT permit you to retain the original copyright notice on the derived work.
You may say that the original work is copyright of the respective owners and that this is a parody work. But that's not what the site is doing. The footer contains the original, unaltered copyright, creating confusion as to who owns the derived work. Amazon does not own this, nor do they endorse it, so you're not allowed to say it's copyrighted by Amazon.
