I did join MobileRead. Then I got an email from them encouraging me submit my first post. I thought of this offer. The risk, by the way, is all mine. I send you a $5 gift card and assume that you will order Red Chaser at $3.99.
As for selling email addresses, I've already listed mine.
findjon@msn.com. Feel free to sell it. Sell yours? C'mon, I'm just looking for readers.
