<p>alright the website says that for econ 51d we need "economics w/wsj guide & my econ lab, pkge." what does all this mean? can i just get the book a lot cheaper and then get the stuff from the teacher or should i just go ahead and buy it from duke?</p>
<p>If under the book, it says Required (which I assume it did since its the main text used in the class), then you’ll probably need all of the components. What you might want to do tho, if you have found a cheaper version of the same book without whatever “my lab” is, is to email the professor (I hear he’s crazy btw 
) and ask if you do need everything within the package. </p>
<p>And see if the Duke Textbook Store has it used.</p>
