The Indianapolis-Marion County Public Library's "Friends of the Library" organization holds, about three or four times a year, a gigantic used books sale. Many of the books are weed books from the library, but many, many of them are donations. They call these sales "Second-Hand Prose". Hard-cover books are generally a dollar, and paperbacks maybe 50 cents, with exceptions for a few certain types of books which cost a little more.
I sort of live from one Second-Hand Prose sale to another. I can go through the MOB that shows up and come out with two large shopping bags of books to feed my habit for $30.00, which will PROBABLY carry me until the next sale. In a commercial bookstore I'd be lucky to get two hardcover books for that.
