I am interested in getting a classroom set of chapter books, but was wondering if anyone knew of ways to get them cheaply. I got an email from Scholastic about their dollar days, but the books didn't look great - mostly holiday books or Goosebumps. Usually we all read Island of the Blue Dolphin together, but this year I have a couple of kids who were retained and already read the book last year. While it wouldn't hurt them to hear the story again, so much of the impact of that book is the element of surprise, and I wouldn't want any of the cool details "given away" in advance. Does anyone have any tips on where to go to buy a bunch of books cheaply? Thanks, everyone!
