Unfortunately, eventually Amazon decided they didn't like me and cut off my API access. This was because I was doing too much scraping of their service, and because they said the design of my site was causing it to falsely report referrals to Amazon. (Still not sure what was causing that exactly.) At any rate they shut off my API access and I haven't had time to come back and revisit the project since I have been working fulltime.
Best of luck with your site, and watch out for sneaky Amazon restrictions.
Congratulations!

Also, where do you get data on new and best selling? Is that just the "popular" breakdown on Amazon?
And
Like you said the "new and best selling" is just the popular breakdown for each category. Though there isn't one for "All Departments". We'll work on that:)
