Right now I have a website setup that accepts paypal. As soon as the customer pays they are redirected back to a page of our website where they can download the book. This is probably not the best method because as soon as someone purchases the product they could give the download link to anyone else for free. I am interested in selling the ebook on clickbank but am not sure how to setup my site to work with clickbank. I have read some of the FAQ's on their site but still do not understand how the consumer gets the product. Are they just redirected to the download page like how I have it set up now, or is their a way to make it encrypted so that they can only download it once?
