Kelle,

First of all.. RECONSIDER Paydotcom. Too shakey.

Secondly, it sounds like you know how to upload your product to your website, so all you have to do is: a) build a "thank you" page for your site, and two, on that thank you page you put a download link for your book.

ie: www.mywebsite.com/mybook.pdf

The buyer then right clicks on the link, and is able to download the pdf.
