I bought a pair of 527s off of Amazon a year ago and was very happy with the fit and quality.  The second pair that I just purchased seem to be a completely different type of jean.  When I did a side by side comparison, the second pair was:  way thinner material, a different fit, shorter pockets, different tags(some looked like they weren't Levi standard issue).  The size tag on the rear seemed to be miscolored and had a different image than previous Levis.  Either Levi's has gone down in quality in the past year or the most recent pair I received was not genuine.  I will be looking at a local store for my next pair of Levi's.
