<p>I always buy my books used online (half.com or Amazon). Rarely has the Pitt Bookstore had the cheapest book.</p>
<p>I never bother to buy the book new (unless the difference between used & new is a few bucks) because…honestly, I’m using the book to look up the homework and some formulas, it’s not <em>that</em> essential. </p>
<p>Then again, this is for my engineering/math/science books. Humanities may be a different story.</p>
