<p>Microeconomics (Pkg), Krugman
Worth
Binding Kit/
ISBN 1-4292-0551-2</p>

<p>Its a $122, can anybody tell what the difference is between this book and the one I’m showing below other than its $72 cheaper</p>

<p>The main difference is that there is now a 2d edition from 2009 which is purported to be an “extensive revision” of the one from 2008 (and before) that you see for sale on that site. “Extensive revisions” is a textbook publishers claim that often applies to just a minor updating in a few spots done mainly so they can sell new books, but I do not know what changes have actually occurred.</p>
