I've never bought them, I've prowled about, looking at their descriptions though. These look great. Short modules, regulated gameplay for balanced characters, this looks like something that I would be entertaining if (here is comes) Paizo would publish these in print form.
I know, they are available in PDF. I buy things for my players (munchkins, all of them) at the two FLGS's and if something I find online I can't get through them, I happily buy it as I have here (waiting for Testament d20).
I would be thinking that the society scenarios would be a great $50 hardcover that would be perfect on my shelf. Season 0, 1, 2, etc...each get their own hardcovers...I am more than likely repeating something that has been mentioned before, but it is a vote for it.
I adore the products you as a company churn out. I'm asking for one more.
