While expensive, I find that I print in full color each adventure, and like the idea of reducing duplication. I paid some .49 cents for each page of Dying Skyseer, which was probably excessive, but I like the high quality printout.
Yeah, like Ryan said - we sell the softcover versions for half that price.

Each adventure has a softcover version a couple of weeks later.
