One of the beauties of digital distribution is that you can give stuff away, at little or no cost to yourself. If you're trying to promote a series of books, reducing the price of the first to 99c - or zero - can hook new fans and increase sales of the whole series.
So, what's my experiment? Right now, Hal Spacejock book one is a free download on Amazon.com, Smashwords, B&N (Nook) and iTunes
Overnight it hit #1 on Amazon's science fiction category, and #2 in humo(r). They maintain separate lists for paid & free books, but there's a kicker ... the free and paid tables are displayed side by side on Amazon's bestseller pages.
Gaining exposure is the toughest challenge most writers face. If you're prepared to give away the first book in a series, or perhaps a short story or two, it could be a cost-effective way of promoting all of your published work.
Has anyone else tried free? If so, how did it work out for you?
