Compare this to UPS/FedEx. Generally, there won't be any lines and you can be in and out in less than 3 minutes.
I've shipped something like 3000 packages via USPS priority mail over the last 3 years, and there have been a grand total of two that have gotten lost (and I'm pretty sure that one of those two was a customer ripping me off). That's a much higher success rate than I've gotten with FedEx & UPS, at lower prices.
However I absolutely loathe, beyond description UPS. I wish Amazon used anything but UPS for prime, it ruins the whole experience.
No need to "swear", they've been caught in that exact act several time by people who'd cleared their daily schedule entirely (or taken a home-work day for office drones) to get their package, either catching them trying to leave after having pinned/dropped a notice or plain not saying them the whole day.
And that's beyond their basic "rules" such as a home number not being clearly visible from the truck means you don't exist and fuck you very much.
Canada's low and spread out population has to count for something in this argument.
It's all funded from postage.
This is an often repeated myth that is very mistaken.
You really want UPS doing to daily mail what they do to packages?
The US should remove all the mandates from the Postal Service and all of the subsidies and open up mail delivery for competition from FedEx and UPS.
However, I don't think it's out of the realm of possibility that they will come to the taxpayer looking for a bailout soon.
