I noticed that this book for the Kindle costs $864, which means it costs more than 2 Kindles. I guess that's a bargain compared to the list price of over $1,000. So I decided to sort the Kindle books by price to see what the most expensive one is.

And the winner is: Selected Nuclear Materials and Engineering Systems (Part 4). The Kindle edition costs $6,431.20. And that's a $1607.80 savings off the list price of $8,039.00! Never before has the one-click order button felt so terrifying.
