<p>D ended up switching to a different calculus class right before classes started, so that was the one expensive book she returned. The book she needed for the new class was on Amazon for $30 to rent (no custom) and is not due back until Dec18th. However, D is taking the next calc level in the spring with this same professor who is actually a bio professor. The calculus book and class is designed for biology majors, so the problems are all related to biology. Well now D will need this same book again that she is renting now. I probably could have bought the book for $70 ish had I known. Do I send it back to Amazon and re-rent or will they let D re-rent it without sending it back? </p>
<p>D’s campus bookstore will provide the ISBN number, author’s last name and an abbreviated title when the course code is entered, but if the book is part of a required “custom” package with a required online access code, just having the ISBN doesn’t help to find a cheaper version. i tried to find the regular version of some of the books in case the professors said the online code wasn’t needed, but I had no way of knowing if the book I found was the same book/edition the professor wanted. I was worried D would end up with the wrong book or end up reading the wrong pages, so I paid the premium prices. Ugh…</p>
