If you don’t like buying from CreateSpace or Amazon, don’t worry. Just go to your local bookstore and ask them to order you a copy. They should be able to do it.
Also, if you buy the trade paperback edition new from Amazon, you can get the Kindle ebook version with it absolutely FREE! Since the ebook version is $6.99, I think this is a pretty good deal if you want to get both versions but don’t want to spend $24 for both of them.
