They're both $9.99. Even at that price I make less per sale than I do on the Kindle versions of the book (which is kind of crazy when you realize that the Kindle versions about a 1/3 of the cost.) But I just couldn't justify pricing them above $10. So $9.99 it is!
At least two independent bookstores have offered to carry the books, so soon they will be available locally. But until then, if you don't want to read them on your Kindle, here they are in paperback.
