I need help with buying textbooks for Chem 142.
I went on Uloop.com to check it out and personally I would like to
order them online and get it shipped. But anyways
on sites like amazon.com and half.com, the chem 142 books are
published in 2007, while the books that students were selling on Uloop.com
are published in 2009, is there a big difference that I just HAVE to buy
the 2009 one? or can I just buy the 2007 published book.
And if anyone knows any other good sites for buying textbooks, please share ! (:
