I've generally had good luck - and it seems "luck" is the operative word - with USPS, incoming & outgoing.
A couple of things late getting where I shipped them, but not as bad as y'all are reporting.
But they do weird things around here; there are days they just don't come down our road, and mail arrives at any hour from 11AM - 6PM.
For years, a guy over a mile away has occasionally received my mail, and I've received his, because we both have 259 in our address.
His street name and mine have nothing in common.
It seems the postman holds my magazines until he's done with them.
As much as they charge for shipping now, you'd think things would improve, but Noooooooo...
