The publisher margin looks about right. It's halfway between 3 and 4 slices on a Papa John's large. 3 slices is a bit too little, but the 4th always makes me wish I stopped at 3. 3.5 might just work.
I'll have mine with pepperoni, italian sausage, green peppers, and onions, thanks. Oh, light on the cheese. Almost non-existant, sort of like actual retail margins.
