<p>So I’m trying to buy my textbooks online but as I just learned this might be a bad idea. I’m mostly using amazon and once I placed the orders, I checked the co-op site again, and my professor’s required books changed completely. I can save up to 50% when I buy my books elsewhere but I panicked and had to request a cancellation on the order not too long ago. I’m really afraid to get more books because it might change but I need to order my textbooks now, what should I do?</p>
<p>Most textbooks won’t change. Don’t worry about ordering online in most cases…</p>
