Help with Psychology Book (Kosslyn)?

Question

So I have to buy "Psychology in context" and in the college bookstore they are selling the "customized" version for $124 ....on Amazon they have the "normal" version for 1/2 the price....Is there any difference between these two books? Should I buy the amazon one?

Here is the link to the amazon product: THANX!

Answer 1

So, are you trying to decide whether to spend a lot of money on a 'customised' version, or half that on a 'normal' version?
Do you really need someone to tell you what to do here?
