half.comI have never sold any of my engineering books since I started. No sense, they always lowball you and it's never worth it. I have also in the past borrowed some books from friends ftw. Books are expensive.
I've never lost more than $10. Usually I wind up losing a couple bucks after I sale it back on there. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
