I must be the exception to there wonderful service I keep hearing about. I ship all over the world for a living for over 20 years when United Parcel went on strike we had to ship with the post office it was a nightmare . As far as using a different carrier at least UPS honors there claims besides that Fed Ex and UPS are moving there packages for them now so I say cut out the middle man.
Wait a sec...you ship all over the world for a living for over 20 years?
Is your company a competitor of USPS?
Maybe your delivery person is trolling you.
That's actually a pretty good joke.
