I'm hoping to publish a book in July or August through Amazon, probably with a paperback option as well as E-book. There's been some people who've really helped along the way, and with another huge wave of reviewing before I publish, there's gonna be a lot of people who help. I know that Betas mostly work for free, but I want to give back just a bit by letting them have a copy of the book, preferably for free.
So, is there a way to get a dozen or so 'free codes' to give to the people who've helped the most when publishing through Amazon? Reduced price works as well but free is better. I'd like the codes to be for the paperback version rather than ebook because you can normally get those for free with Kindle Unlimited.
