Back in November 2011, I participated in the Indie Book Collective's   Blog Tour de Troops promotion that consisted of several dozen writers who gave Smashwords coupons for a free ebook version of your book to  readers who left comments on our blogs in support of U.S. troops. I had stumbled across a tweet advertising that the IBC promotion would be  starting in a few weeks and I decided to sign up. The $25 entry fee  would be put toward a Kindle that would be given away in a drawing to  one random reader who had signed up for the IBC newsletter during the  promotion or left a comment on one of the participating author blogs.
