Stop by Amazon Local this week to get your free e-book voucher. This voucher allows you to purchase one of 25 e-books for $1. I just did a cursory glance and didn't see a book on the list I was interested in, but it's worth checking out.
Don't forget to check with your local library and see if they have a free e-book loan program! Our library does. It allows me to check out up to 15 books at a tie via Kindle! The best part is you don't have to own a Kindle to do this. Any device that you can install the Kindle reader on makes you capable of getting e-books through Amazon!
