Man, that's a loaded question!
Wish you had asked a couple of months ago. I sold Dale Roberts 6 or 8 (can't remember now) short boxes full of pulps at Heroes Con! He picked them up for a friend, so I'm sure their gone.
It depends on what you are looking for.
Cool covers (and there's lots of them!)
Certain authors Like Burroughs, Howard, Bloch?
Certain Series, like Weird Tales, Argosy, Spicy titles?
Or just what ever jumps in front of you?
Lot's and lot's of mid grade pulps to be had for less than $50 each.
