I run a mail order business. I process over 160 orders a month. I have not had a single package that was actually lost for the last several years. I have seen some examples of Post Office incompetence regarding packages that were returned to me, but overall, I regard the system as efficient.
I ordered socks from Burlinton, NC on Dec 3rd. Thay are still ‘in transit’ today I could have driven oner there and picked them up in much less time than the ‘mail’ is handling them. I’m in East Tennessee and Burlington is not that far away. The tracking shows they went through Atlanta a week ago, on their way, supposedly, to East Tennessee.
