Amazon KDP offers authors a single book proof copy of their book before purchase for free. However, you are NOT getting an exact copy of the book you end up purchasing. You will be holding in your hands a copy of your book with a "Not for Resale" watermark, no hardcover option, and a UPC code added to the back cover. Additionally, you'll have to pay for shipping.
Here's what else Amazon offers:
- Three uncoated paper stock choices
- Inkjet printing
- Basic, automated file inspection
- Limited support via email
- Availability only to KDP
