I have mailed a lot of packages, even APO when DD and family were in Japan, and have learned that postal workers do and say different things. I have taken my package and walked out the door. So now if possible, I use the flat rate packaging and pay online. The padded flat rate envelope is $5.10 with free delivery confirmation if you use the online postage method and you can list the recipient's email so they can see the tracking, too. All of the FR packaging is discounted postage with free delivery confirmation.
