Re: At what point is something lost with USPS?
So, I did call. And I was actually really surprised by USPS, in a good way!
They have no idea where it is, still. But, they apologized right away that it was missing. No run around. And then they said someone would get back to me, which I was like, yeah right. Then two days later my local post office called, and said they have been trying to figure out which plane it was on leaving Michigan, and are researching what may have happened, and hope that it still shows up. He apologized again, said he sincerely hoped it wasn't something Christmas-related, and giggled when I told him it was cloth diaper covers.
In any event, no package, but I was impressed by the level of personal responsibility and service provided by USPS.
