Textbook prices

I am appalled by the prices of textbooks. I just bought a Microsoft Access book for $94.25, The Microsoft Office software package doesn't cost that much.  It is ridiculous, how do these universities expect for students to be able to pay for all of this. $94.25 was just for one textbook times that by 5 classes a semester plus tuition and room/board and food expenses and you are looking at a lot of money.
