<p>for econ I was not able to find the 4th edition of the book (principals of economics) I was wondering if i bought the 3rd edition would that work too?</p>
<p>I was wondering the same thing for honors chemistry. Can I stick with the 5th edition without buying the 6th?</p>
<p>your professor is going to give you a much better answer than anyone on this forum can ...</p>
<p>all my friends from chem6ah/bh/ch got the new edition. i got it too cause i figured, hey i'm going to use it for the whole entire year, why torture myself?</p>
<p>(shameless advertising: i have the chem honors book plus solution manual if you are interested :D in great condition.. i had book covers and all)</p>
<p>What edition do you have and what are you charging?</p>
