… offered to sell 50 copies of my book
at cost, to a conference organizer, for an event in July at which I am a speaker.
It’s an arrangement that works well for all of us: She gets to give the book away as a bonus to those who attend my session; I get more visibility; attendees get my (fabulous) book.
Another benefit of developing valuable content (doesn’t have to be a book): You can then give it away for free (or close to it) as the situation arises.
