NEW KINDS OF MYSTERY BOXES

I'm close to putting together two new kinds of mystery boxes.  One would be trade paperbacks and the other hardcovers.  These would be a 60/40 mix of comics stuff and non-comics stuff.  I figure I could get between 20-30 books in each kind of box.  But the shipping would be more expensive and I'd have to factor that into the price.  What would you - yes, you - be willing to pay for such mystery boxes?
