You can often get bulk discounts on books from the publisher. My Dad was very fond of Richard Bach's "Illusions" when it came out, So he bought several cases over the next couple years, to give out copies to people. I've never bought cases, but I've given away "spare" copies of numerous titles I'm fond of. There's several titles I'll buy used if I see them so as to have backups for giving away or damage to shelved books. NFI how many copies of "Illuminatus! Trilogy" and "Lord of the Rings" I've given away... dozen or more in each case.
