IMO - science majors should "splurge" and get their books new. My daughters chem books will be $200 each from the school bookstore - the good news there is that it's a two semester course and will continue with the same book in the spring. Lots of science courses are like this.
The biggest rippoff is with English and history books. My d's English prof wants her to buy the "50th Anniversary edition" of Death of a Salesman - gimme a break.
If it's any consolation to you kids - this problem has been around since before you were born. Back in the day my parents and I would complain about what a ripoff college text books are. For liberal arts classes - never buy a book before the first day of class. Never buy "recommended" books.
I had classes where the prof would list 6 "required" books to buy and the first days would tell you that 3 of them were for your "personal" enjoyment.
