You properly terminated your membership in a CD club four months ago, yet you receive a
compact disc through the mail from the club. It is the new release of your favorite artist. You play it repeatedly for more than a month before you receive a letter from the club stating that it made a mistake in sending the disc to you and asking that you either return the disc unused or pay for it. Do you have an ethical obligation to do so? Do you have a legal obligation to do so?
