The following comment is based on the fact that OP shared a link to his website in one of these comments.

Your Website

The Homepage - Your jumbotron area is pretty good. I really like the animated before/after picture scrolling thing you've got going on. It very quickly illustrates what the product is. I'm not a huge fan of your calls to action though. The button is great, but the language "Try Now For Free" to me gives the impression that you want me to sign up for a free trial of something. When I see a box right below that saying "Buy Now," it just reinforces that concept, especially when I don't yet know what I'm buying. At this point, for all I know this is a subscription service model with a free first month trial. After some poking around I realized that the individual download pages are free and the books cost money, but I should be able to figure that out almost immediately for a product this simple. I would put two big buttons in the jumbotron area (different colors so they stand out from each other). One would say "Deluxe Books [line break here] $9.95" and the other would say "Single Page Downloads [line break here] FREE" and link them out to the appropriate places. I would then get rid of three boxes below the jumbotron altogether (move search to the nav bar) and use that space for something more worthwhile like showcasing your top selling books or most downloaded single pages, or both.

Free Product Pages - By this I mean the pages for your free download items such as this. There are not really any calls to action here. Instead of having the images here link out to the PDF, I would have them just open a larger version of the image in a lightbox (make sure the lightbox is easy to close). Then once again I would have two buttons; a more muted one that says "Download Free" or "Print at Home Free" or something like that which links to the PDF, and then a bright and bold one that says "Get The Book" which links out to whatever book that image comes from.
