We market eCourses and eBooks and ran across a cool way to present your product in a "page flip" format using issuu. The feedback from our customers has been solid to say the least. Their service is free! Check them out at www.issuu.com. We also created a YouTube that we use in our marketing showing how it works. Check it out at http://www.youtube.com/watch?v=zq-RJ9XSSeA.
