<p>Is the only option buying? I am asking because as far as I understood, when you rent books, supplemental things like DVDs and access codes are not available. </p>
<p>college freshman here, so any help will be appreciated..</p>
<p>In my experience, access codes for sites like that could be bought separately (though sometimes they’re expensive) if your textbook didn’t come with one.</p>
<p>The code, however, is cheaper to buy online as opposed to buying the code from your bookstore (at least it is at my school). My only experience is with WebAssign though.</p>
