me too man…the bookstore prices are absurd and i’ve noticed that alot of members either have or are taking physics / engineering courses, so i figured i may be in luck.
OT: if your taking any other physics and math courses i have some old books if ya need em.
try valorebooks.com They ussually give pretty good amount back, depending on the book. I know a lot of people that work there and can get you a promotion code for 5 % more if you decide you want to sell any to them. If you go to there site you can type in the ISBN and it will tell you how much you could get. pm me if you want that code.
