What are units of books called if you're buying them in bulk? Cases? Crates? Boxes?

If you were going to buy/sell books in bulk, what would they come in? Would you quote the price per box? or price per case?





I'm doing this for a college project... I'd hate to use the wrong term and sound like an idiot :)What are units of books called if you're buying them in bulk? Cases? Crates? Boxes?
I my experience, my publisher only called them boxes of 25, 50, 75, etc. They always went in bulks of 25, not sure why. They also never really stuck with one unit, just either said box or case.


But they were a publishing, not a printing company. Maybe printing companies have their own set of terms, and it depends on who you're addressing.
