Used Books

<p>I'm trying to save money on books, obviously. I'm considering buying from amazon and chegg, listed as "used" as much as possible. Is this a good idea, or am I more likely to be screwed by getting incorrect books etc.?</p>

<p>Just make sure the ISBNs match up, you are eschool right? You can also email your professors, they are used to 1st years emailing them about “can this version be okay” etc.</p>

<p>Thanks, yes, I am Eschool! You’re tons of help btw!</p>
