Selling used books question

<p>I just bought one of my textbooks new (I didn't really wanted to, but anyways) and I'm pretty sure I'm gonna try to sell it at the end of the semester.</p>

<p>Can I still write or highlight in the book if I want to sell it? Where can I sell it at the end of semester?</p>

<p>Bumpbumpbump?</p>

<p>Both are fine.</p>

<p>Sell them at ned’s, student store, online.</p>
