Query: Can't purchase book

The price of this 2006 book is $16.00 for the Kindle. Paperback is only $10. That's too much for the Kindle version and that's the only way I read. This is really a note to the publisher/author, and not a review of the book, which I would like to read.UPDATE: I see that the Kindle version is now the same price as the paperback - $10.88. Kudos to someone for listening. When it is $9.99 or less, I can buy it.
