Just yesterday I returned home to find my driveway littered with packages, all delivered by USPS. It looked like a crime scene, but lo and behold all packages were there and contents intact. Why the delivery person didn't leave them on my front porch is a mystery to me, but quite common. I have a surveillance camera on the front door, and I've watched countless delivery people try all sorts of things on my front gate (up to and including trying to rip it off its hinges, but never simply pushing it open) before stacking my parcels outside the gate, tossing them over the gate etc. Amazingly I've never had any breakage with all that.
One shipment that did arrive severely damaged was, of all things, a road case. The shipping box didn't look too terribly bad, but when I opened it up, I found that the road case inside had been spindled by something with enough force to make a 2" hole all the way through the broad side of the case. In addition, one of the metal ribs had been bent into a Z shape, and numerous rivet heads had been sheared off. In the 40 years that I've been using road cases, I've never seen such extreme damage to any single case. It was a good reminder that the sub-$1000 cases that look as strong as the well-known brands...well, you get what you pay for.
