...instead of buying a book in one discrete transaction, you could subscribe to a book, with the expectation that an author will continually add to it. This would be more suitable for nonfiction than novels, but it's also possible that a novelist might decide to rewrite an ending, or change something in the middle of the story.
Finally they can "special-editionalise" the Star War novels too!(Yes, editionalise is a real word, my Kindle says so)
