Math 53: (Yes, this is the current Math 53 textbook, blue cover w/ the turbines)

Buy: Used at the bookstore is $166, new is $222. The book is pretty much brand new with a few pencil markings. You can get a more used, beat-up version via amazon for around $100 + shipping and wait up to 2-3 weeks and have to wait in line at the post office. Or you can buy it from me on campus for $140 immediately, and resell it at the end of the quarter for probably a similar price, since math 53 is offered every quarter and is always in demand.

Rent: New rental at the book store is $144, used rental at the bookstore is $106. I will rent to you for one quarter for $70.

Sort of negotiable, email me.
