I was so skeptical about ordering from this site at first, especially after I read the reviews & seeing how cheap everything was! But I needed 2 more books for Medical School and they were just $15, what did I have to loose?! They came in, before the expected date and they were in PERFECT condition! The books didn't have a scratch on them and the workbook wasn't wrote it at all! I will definetly be ordering from here more often
