I packed up a reloading press a few years ago to be shipped out. I cut cardboard to nest the press in the box. Double boxed it and taped it shut with fiber reinforced tape.. Took it to the Post Office it weighed just under 50 pounds if I remember right. I paid my shipping charges. The fellow picked up the box turns and throws it towards the canvas cart packages go in. It landed short and hit the floor. He walked over grabbed it up and tossed it into the cart. Kind of upsetting to pay all that money for shipping just to have what is being sent carelessly abused.
