One of the things I'd like to see in your online previews is a table of contents for the product. When I'm shopping for my next gaming purchase, I like to get an idea of just what it is I'm going to be purchasing. If my FLGS doesn't have a copy to flip through, I have to rely on the information that comes out of the publisher, and if I can see what information is contained in the product, by way of a ToC, what might be a Pass is more likely to become a Purchase.
