Our daughter Ceptember suggested this website, sortfloor. She is gathering books for her classroom and ordered several books. One had a bent cover, and the others were in perfect brand new condition. The prices were good.
The site is a little difficult to navigate. I pulled up Amazon and typed in interesting titles that I had found on this site. By doing that I could get a book description, rating and reviews. I found some fun ones and am happily waiting for them to arrive.
