i bought my books (used of course) online at our own bookstore and they sent me a new one and charged me for a new one...

i went onto half.com and just bought the instructor's edition, brand new, same edition for over 40 dollars less.

so when i resell it back to the school, i can probably get most of the money back.

im a GENIUS! (not really, but im pretty happy) im also selling my engineering books 2morrow for another 50 bucks, w00t.
