How do I send a book to my Kindle from a computer?
First, download the book from the member’s area book download page. After it has been downloaded, unzip the file. Double-tap the file to unzip.
Open your email program and attach the file you prefer from the unzipped book file. If you prefer, you can rename the file before emailing so that it will appear on your device as the name instead of the SKU.
For more information on emailing the file to your Kindle, Amazon has a page to help you:
