Unfortunately I live in Canada, we don't have USPS, and Canada Post's options pretty much amount to "Screw you, you're stuck with us!"
I asked if I could have them just hold the packages, and they said no, they must deliver them to the correct address.
We asked if we could get the delivery person to come to the side door of our building (where people can actually hear the door, rather than the front door that nobody is near) and even with a sign telling all delivery people to use the side door, Canada post told us that it is against their policy to go to any door but the front. (UPS, Purolator, and Fed-Ex can all figure it out)
I've also had the tracking information show a package loaded on to a truck for delivery, and then scanned back in to the depot, with no attempted delivery at all five days in a row. and I've had 2 packages go completely missing never to be seen again (both were ones that weren't "tracked")
As for UPS, I've had their "guaranteed overnight delivery" take over a week, including them saying that they had no idea where the package was (but that it wasn't lost, because to declare it lost would take another week of investigation) and still refuse to reimburse the shipping costs, or provide any other compensation (so much for the "guarantee") (we shipped a second package to replace the first, and they both showed up on the same truck eventually)
I've also had DHL "accidentally" ship a package ground when we paid for air shipment, again, no compensation for the extra 4 days it took that package to take what should have been a one day drive.
and Both Purolator and FedEx have repeatedly delivered our packages to the wrong address, or other people's packages to our address.
About the only courier company I've had any real success with is Greyhound.
