Steve,
If I search for your book using the Amazon.com search, the result for your book links me to this page:
Amazon.com: Personal Development for Smart People: The Conscious Pursuit of Personal Growth: Steve Pavlina: Books
It doesn't have a buy option, unless I go to the "hardcover" copy of your book.
Seems like an inefficiency you may want to get rid of. You want the buy option and general info about the book to be nice and clear, I'd think.
But then, perhaps this is secretly good, since it acts as a nice filter for the smart people.
(But then, smart people aren't the only people who need your book. And we need non-smart people to buy your book, become outraged by it, and sell it cheap second hand so the broke smart people can buy a copy.
<--- that was too much fun.)
