Using USPS is like playing with fire. Those who continue to praise it just haven't gotten burned yet. Bust rest assured, you will. They are terrible. I make sure to avoid them like the plague when buying items online.
Over the years I have lost count how many times they have screwed me. Lost packages, damaged packages, packages left in the rain, packages delivered to the wrong address (even though I have been at my current address for 30 years the idiots still cant find it sometimes), insufficient tracking information, etc... I mean the list of errors is comedic at this point.
They are truly a terrible entity.
