I disagree. I’ve never had a problem with UPS including shipments of powder and primers. On the other hand FedEx seems to misplace every shipment. In the last year they lost an entire set of tires and were 4-5 days late on every other shipment (including the replacement tires). Every shipment shows it will arrive today then dissappears into limbo for 3-4 days before finally showing up.
Sorry! I mistook UPS for the USPS. We have done much online shopping, for ourselves and neighbors, thanks be to God, and UPS has provided the best service, including returns, as with the RMA on the box you can just give it to the driver, and see it credited a few hours later. Good updates if you are signed up, and drivers are good drivers and efficient. Same old delivery trucks as years ago, but in very good condition.
UPS usually comes by at least twice a week on our street in this "low income" city, and the only complaint I have is the none of the delivery persons will ring the door bell right in front of them, though UPS usually leaves packages inside if door is open.
Walmart uses FedEx and drivers often just toss boxes on the porch, and as Walmart (lowest prices on many common goods) packages poorly, sometimes contents are spilled.
As for the USPS, the postal delivery workers have overall been nice and personable and good to work with, but the system is the least reliable. Local PO as well as the main distribution typically answers phones, and poor response at the Fed level. Amazon shipped auto parts a few years ago and USPS lost them, but it took many calls to actually talk to a person and to find that out. Yet Amazon made good for them. On the other hand, I once placed a return RMA on the wrong box and gave it to the postman, and (when in my chagrin I realized my mistake) I tried to get a hold of the local PO or main distribution to try to stop it or find out what to do, then I could not. Even going to the main main distribution that day could not stop it, nor did they know what driver got it yet the workers were considerate and tried. And I gave them the correct package with a duplicate RMA, and both ended up at the same place. No problem in the end, thanks be to God.
