Just signed my novels up for a program on Kindle Direct Publishing (i.e. Amazon) that provides electronic copies of my novels at a discounted price for anyone who purchases a print copy. I think this is a cool idea, and a nice benefit for those people that are springing for the higher priced paperbacks that I have printed by CreateSpace.
The program is not yet live, but according the email I received, it should be in a matter of a few weeks.
For now I've decided to price each copy at $0.99, which means that if you buy the paperback, you can get the electronic version of my book for only $1. Will see how this works out over the coming months, and hopefully comment back here.
