I was referring to other publishers. I recall Greg Pak's Battlestar Galactica #0 selling for $0.25 (Dynamite Entertainment) and StarCraft #0 given away for free (Wildstorm) and Dungeons&Dragons #0 selling for $1 or free at NYCC2010 (IDW). The concept is that you give a promo comic to tease in new readers for a low price. Makes more sense to me than starting over at #1 every 8 issues. I wish I could remember more examples of this situation.
