get the best price, if you purchased the book on the Amazon site. Larken sells the book on Amazon for $12 plus $3.99 shipping. But if you go to his own website and buy it there, it only costs $10, shipping included. If you buy multiple copies, you get even better prices. I pre-ordered 10 copies from him before the book was even published for $91, and he sent me an extra one for free.
If you're a fan of his, you should explore his TMDS blog -- there are some incredible essays tucked away in there. Also, I've posted another excerpt from The Most Dangerous Superstition here on the DP.
And thank you for the kind words about my Rights Are Santa Claus piece. I'm still waiting to hear if Strike the Root will publish it.
