Levandosky Linear Algebra book: $50 (good condition)
Physics for Scientists and Engineers: A Strategic Approach Vol. 1 + free study guide: $40 (good condition)

Also, I'm selling Taylor/Weerapana: Principles of Economics 7th ed. used in Econ 1A (and perhaps used in Econ 1B?). Bought new for over $200, I'm looking to sell for $140 (great condition)
