I'm giving Chegg one star because half a star is not available. I bought a book, they sent me the wrong book. I informed them of the issue, they supposedly sent me back the right book. I did this 6 times, so I have 6 wrong books. I called to complain and found out they charged me for all 6 books that they won't refund me for. These people are useless, don't waste your time. Go to Amazon. F@%$ Chegg.
