I have now saved $83.26 on books by buying a Kindle.
Admittedly, I would not have purchased some of these books had I not gotten a Kindle… And that would put the figure in the $60s. But I’m sure glad I bought those books (like Nothing to Envy, Stalingrad, and 1776) and read them—and that reading wouldn’t have happened without the Kindle. It makes reading good books in snatches much easier.
