FYI: I did get Going Postal for my Kindle and am loving the book even more than the TV movie. 
Yay! Making Money is good too, and that would be the next logical step. Does the Kindle version have the cool chapter illustrations?
Nope, no illustrations on the Kindle version. They tend to not do them because of the limitations of e-ink. It's a shame because I've gotten a few in Kindle format from the Gutenberg Project that have nice illustrations and you just have to load the book into the Kindle app on the PC to see them well.
See this is where the adaptation is superior to the book, I can take or leave Susan, but I love Michelle Dockery
Don't tell me Susan in the movie is more interesting than in the book, I was thinking about that one next just because of her character, and secondly, Death....
