Several years ago I ordered promotional hand fans for two of my Logan Hunter mysteries. Since it was summer and I attended baseball games nearly every day in temps up to 100+ degrees, I gave out hand fans to those other spectators melting alongside. The fans had the Just North of Luck cover and others the Hell Swamp cover. They went fast, with my web site and short excerpt on the back. Folks have already asked me this year if I have fans. As a matter of fact, I ordered Genesis Beach fans and Slightly Cracked ones also, although I'm holding those back until the book releases.
Does everyone zip over to buy a book? No, but many do, and it's a fun way to promote and keep cool. I do save enough to take to books signings and conferences so that I can give a fan to those who purchase that particular book.
What do you do for promotion?
