I purchased a book for $180 for a class i was taking and then out of nowhere the school forced me into another professor's class because my original professor never published it.

The new professor required a new book that was nothing like the one i had so i took the unopened book to the bookstore just to be told its non-refundable, even though the fault wasn't mine. Schools should be helping students save money not screw them over for pocket change.
