phantom, if the NFLX mailers are not compliant with USPS regulations, then why haven't they been forced to take them off the market? The USPS can't allow NFLX to use them and not allow other companies. That doesn't even make sense. That would be discrimination. Besides, if the light mailers are so much of a problem for the USPS then Fleming should be aware of this problem and he should have been working to get mailers produced that are Tyvek reinforced.
