I have been working on trying to get McGraw Hill to reduce the price of James and Stuart Rachels The Elements of Moral Philosophy textbook.
Allegedly, it might be available at a lower price ($48) if this ISBN is used: 9781307026900
If this works for you, let me know. I am trying to get them to set up some kind of way for it to be ordered online at this lower price.
