What difference does it make to the post office whether it is media, advertizing or steel. They still have to deliver the package, it weighs the same as a media package would, and it's going to the same address? Duh. Just X ray it would be quicker instead of paying someone to open it. As usual the gov has its head up its butt. I don't understand why they give media a lower price. Must have something to do with someone in politics owning a book store or something.
