Price is rarely an issue with our customers as we are all volunteers at a public charity,  and will give books to people who can honestly say they cannot afford them--out of work, single parent, home--schooler, teacher, pastor, veteran, first-responder or active-duty military.  Even at that, they frequently make some kind of a donation.  Being friends with our customers is almost second-nature as we have our love of and respect for books in common.
