Amazon TotalUsed
Add shipping cost to used Amazon products in order to get accurate pricing. Version .35
Adds shipping for "New and used" amazon books to show true used product prices, so you can compare it with Amazon's free shipping on new products (over $25). Works with Books, DVDs, VHS and Music. Props to Sheil Naik for fixing some bugs. Version 0.35
Confirmed working on product pages only. Last checked, and working, on Books, DVDs, Music, and Computer Games on September 18, 2008.

First off, thanks everyone for the comments. Amazon keeps changing things, but it appears that everything is working. Kimball - your example pages are displaying correctly. Shipping prices had changed, too, so that's fixed as well. As for Marketplace, Wish list, and other pages - that's for the future :) . Let me know if you encounter any further problems.

This is not working correctly-- see example page for http://www.amazon.com/Sony-God-of-War-2/dp/B000...; It also neglects to show added prices for unavailable items which Amazon does not itself sell. For example, see http://www.amazon.com/Cast-Two-Disc-Special-Viv...

I only see this working on the product page itself. Is it supposed to work in the Marketplace section, too?

Love it - good job! Saves me clicking. The lastest version works fine for me.

Thanks. I'm trying to add it to the wishlist page, but I'm running into some problems. They're definitely solvable, but I need more javascript experience to solve them.

Great idea. Any chance you can add it to the wishlist page?

Thanks for the comments as well as the update. I'm really new to javascript and thought I had caught the rounding error with the .toFixed(2) function call... evidently not. New version is uploaded and you've got props :)

Here, I made the change for you. Visit http://www.tcnj.edu/~naik2/3858fixed.user.js for the new script with the rounding change. I just added a Math.round() to your percentageChange variable. Easy enough. Please update your script on userscripts.org (and maybe give me some props? :) )

Great script! This makes buying from the Marketplace a lot easier. I love the percent savings feature...really shows you how much you're saving. I did find a problem with it though:
When looking at the used price on a product, (I used Jerry Seinfeld's book "Seinlanguage") I saw the following percent savings:
0.01 + 3.49 = $3.50 (56.00000000000001% savings)
I think that percent can be concatenated as just an integer. I doubt anyone cares about the percent to the 14th decimal place.
