I go to this website for deals on anything that I could use from gardeningtools to sneakers. I found this post today about free e-books from amazon.com and there about a dozen of them. I can't say if they are great books, but they are free and that makes it at least something of interest. Especially with the information they purportedly have. I am putting link in here and am not sure if it will work or if it requires cut and paste. Good luck and enjoy.
