I am selling a book and want to let customers download 8 chapters for free. Currently, I simply attach a file to the button in a section - so, it launches the PDF in a new window and lets them read / download the file.
While it does serve the purpose, I can't track who downloads the file and can't really follow up with them. I want to make sure that they leave their email before they can open / access the file for download (just a quick popup to enter email / subscribe). I know that I can use Digital Downloads for this purpose, but i want to avoid the complicated process of setting this file as a product and having them check it out of the cart (want a much simpler process).
