"I can download that book for free online" pshhh....
Sometimes we get customers coming in that brag how they can just download a .pdf of the book online for free and getting a good deal on a used book is not going to work.
Piracy is everywhere on the internet. There is no doubt you can download a free copy somewhere online and save a few bucks while you squint, suffer, and expose yourself to more blue light than you needed. This is usually against the law. It is not worth it considering how much you pay to go to school and how important good grades are. We always recommend following the law.
