<p>Just buy a used one. Go to a bookstore that sells used books. Or look for ads in newspapers that sells used books. I got a whole bunch of books by buying used books in bookstores and looking at ads. Don’t ever do what rayankees94 is suggesting. That’s very bad.</p>
<p>I live in a society filled with Koreans (I’m a Korean myself), so there are a lots of used bookstores that sell used SAT books. And Koreans here sell their SAT books when they don’t need them, so I bought them.</p>
<p>I hope this has helped you!</p>
