Sorry to hear you've taken one on the nose , talesof ( you too , D&b ) .
I too have had zero incidents with priority USPS shipping , as to non-delivery (so far) .
Part of the year-long problem here in the Northwest cities , is the fact that dopers/theives cruise neighborhoods looking for packages left on front porches .
Their 'activities' increase during the year-end holidays .
I tend to go overboard with shipping ... all the bells & whistles that a few extra bucks can buy , even sometimes when it does not make the greatest sense .
I figure that I'm placing my reputation in the hands of anonymous government workers , so the more I can keep track of it , the better .... and have a paper-trail to fall back on .
The exceptions have been when I've sent 4 crates of books , via USPS 'book rate' , and one of them took 4 weeks to make it to the East coast (all to the same address , mailed at the same time/place !) ... two others arrived after 2 weeks , and one after 3 weeks .
Earlier this year I bought a pretty fancy piece of art (wood & glass framed) from the N.East U.S. ... the sellers' shipper sent it via USPS (not the means of shipping I'd specified) ... I have never recieved a more beat-to-s##t package in my life ... there was not a 90 degree corner anywhere on it - no exageration .
The mailman had to witness me opening it ( painting was undamaged , thankfully , due to the fact that I'd specified that it be packed in a custom-built masonite & wood "crate" - which the misguided shipper had put inside of the cardboard & bubble-wrap box - I was internally havin' kittens , opening that one !) .
This was the second heavily-damaged box I'd received this year (both were paintings & undamaged ..whew ) & left me wondering ....how come? .
Oh ... I see I've been on a rant ... time to quit it now .
