Dealing with syllabus error as instructor
Well, you are polite enough to care about this deeply. I think one of your students might be polite enough to help you. As I understand, this &quot;wrong&quot; book actually is the course material in one of your other classes. You can ask in that class if someone who hasn't bought the book would like to buy that spare copy. You can incentivize it with a discount on the brand new book (something like 25 dollars) and you can pay the small difference to the student.
