I am currently in the process of trying to make my book available for purchase on Amazon and similar services. My hope is to ultimately be able to offer my book in eBook, Print On Demand, and audiobook formats.
So far, in none of the interfaces I have been working with, such as Amazon or CreateSpace, is there a way I can see for sending someone a free copy of the book. I have a number of people that I want to send my book to, some in hopes of getting them to give me a promotional blurb, some in hopes they'll give it a review, and some in gratitude for past help on my book.
I know I could potentially send these people a "raw" PDF copy of my written book, or the MP3 files for my audio book. However, that feels problematic to me for a few reasons, which are a little lengthy, but let's just say it would feel a lot better to say to someone "sure, let me give you a free copy of my book on Amazon", as opposed to, "can I email you a PDF file (that you'll have to figure out how to open on your Kindle or whatever because you're not going to want to read it on your laptop screen)?"
If I have a properly formatted Kindle book, can I make and distribute promotional copies? Can I do it through the Amazon system?
Can something similar be done with audiobooks on Audible?
Lastly, what about Print on Demand?
(I realize I am asking about three different formats, which might justify three different questions. If the community feels that's merited, I can go along with that. But, it's all about how to make promotional free copies, so for now I'm thinking that unifies the question.)
