How to give away books

Is this thing still on?

Okay, here's the deal, each year I get 20 copies of a book to give away to our catechumens when I teach during Advent. This year we have a huge OCIA class (which is great!) but, I'd have to get about 40 more copies to be able to give one to everyone, and I just can't swing that.

So (unless someone wants to donate $160 bucks...) what is a fair way to give them out? I know some probably never read them. I'd like them to get to people who will read it and share it.

(It's Why We're Catholic by Trent Horn, in case you're wondering.)

Any ideas how to distribute?
