to return or not to return??

<p>I bought the Calculus 20B bundle and I did already open it and I just dropped that class for another. </p>

<p>I'm not planning on taking the math class again until next Fall...do you think they'll be using the same book? should I just hold on till these until then?</p>

<p>return it. you can buy it online for way less.</p>

<p>Return it. They might switch books, or more probably, switch editions.</p>
