Buy one huge book and use it for two or three classes.

In Japanese class we'd buy a book and go through literally every single word of it eventually. Not a page wasted. That was nice too.
The Calc 1 and Calc2 book is the same as my Calc3 book...with one exception. I had to buy a new edition EACH SEMESTER. The book is hardcover and costs a whopping $130. Luckily I got a dirty-used-torn-written paperback edition for $4 each time. But I pain to those who actually go to the bookstore and pay full price each time.
