Is there an API that can find books from multiple sellers by say, ISBN? It would be nice to easily find the cheapest book from various sellers.

Similar but related, I use this: http://www.cheapriver.com/

It compares prices amongst Amazon: different country sites price things differently, the site above compares them with postage. It's often cheaper to buy from a different country.

Not sure if it's exactly what you're looking for, but I use a Firefox Add-on called Invisible Hand.

http://www.getinvisiblehand.com/

When you visit a product page on Amazon or other retailers, a notification bar will show you the lowest price for that product.
