<p>I need this book in the 11th edition for a class, but really can't spare the $100 for it. I found a 10th edition for much less. Is there any difference that would jeopardize my readings in this class?</p>
<p>Can you e-mail the professor?</p>
<p>Also, is a CD involved? Sometimes older editions, or used books in general, don’t have the CD.</p>
<p>I hope you can make the savings!</p>
<p>Do ask the prof as there usually is very little difference in the editions. But I think that if you put the title and edition into Google, you’ll find it for much, much less- under $50! PM me if you have problems as I may know someone who has a copy to sell.</p>
