Watch out for those sellers that have a very high satisfaction rate, i think its mostly sellers who rates themselves!!!!!!!!!!!!!! (Try to look for the low satisfaction rates to find what the real buyers think)......... You have to be really careful about who you are buying textbooks from, there are a lot of United Kingdom sellers that will advertise one thing and send you the book either extremely late or will gip you off somehow. I think amazon should work on taking out the non-trust worthy sellers from their list or they will lose a lot of customers. Not satisfied at all!!!!
