Carl,
I have a dedicated folder with photos of dozens of ripped, torn, crushed, etc. packages over the past 15 or so years. And while I use the "Priority" option for almost all of my shipping needs (4 this week) I would invite all who read this to seek out some of the USPS mailing boxes from past years.
Leading to:
Also, another conclusion I have reached is that while the USPS is not allowed to arbitrarily raise postal rates without approval they certainly have managed to shrink the sizes and options available for shipping. I have boxes for which the USPS web site no longer has a posted tariff. Hmmmmm. Raise rates? No! But shrink the (especially "Flat Rate") shipping containers? Yup! The "Use Your Own Box" option is pricey. Wonder why?
Hopefully your luck will hold.
I am sending you something in snail mail. Hopefully, too, it will get to you this year.
