Well, from experience I can say that many attention-starved geek collectors made sure the bookstore saved copies of GP for them and they picked them up religiously. I never had anyone even ask for P&P comics. According LKH, sales have been good.

As far as TwiMoms... Oh, dear. Edward is an immoral homicidal sociopath bounty hunter. = Mr. Darcy? Personally, I don't think so.
