Man, after reading some of these comments/experiences, I feel very lucky. I'm on a first name basis with my USPS guy, and the FedEx & UPS drivers are the same guys every day. So, maybe I've built a rapport, or maybe it's a regional thing, but my guys are great. When I'm home and out in the garage (which is 20 days out of the month), I walk out to meet them at their truck and take my package from them. Now, you definitely can tell some packages have had a "rough" journey, and since I frequently take the package right from their hands, it's clear that it wasn't from the last leg of the trip.
These packages face so many opportunities to be assaulted - going from truck to plane to conveyor belt, back on another truck - it's no wonder they get beat up. I'm not excusing the mishandling of our items, just saying maybe a little extra cushion in our boxes and some insurance is in the seller's best interest.
