I once had a laptop backed over by a mail truck, so yeah, sometimes your luck is going to suck. But, good packing gets it there most times. When a lot of hard drives comes in, a little "game" we have at the office is to guess the pass-rate on boxes. A well-packed box will usually test out around 90% passage, more if the sender pre-tests. A poorly packaged one will never do well. I had a pallet I worked through that didn't get much packaging. That was a couple thousand dollars lost for them- at least. It makes me cry to see stuff like that happen. Pack your stuff so that it can survive an apocalypse, and it'll usually work out. If the Post Office screws up on delivery, I can usually take the tracking number to them and have the box located within a couple hours
