I live in Ohio. My nanovna package tracking shows delivery to "Mailbox" in Nebraska on Saturday.
USPS "Email Us" site is "temporarily unavailable" and their phone tree is a complete FAIL.

I think this is not likely the eBay seller's fault, but an amazing USPS error, since tracking is present.
Scam or error?

Anyone with advice or comments?

Thanks, AC8FD

Still waiting for my nanovna, but bogus USPS tracking is not at all amazing.
I have had packages wrongly reported delivery to my correct address up to 4 days before actual delivery.
If you have tracking data from a successful delivery for comparison, you may note where bogus
track has missing steps. I suppose these result from wrong barcode scans...
