Is our USPS Tracking # Trackable

[Buythatcard]

I use to wonder the same thing.

Several years ago, I started using a different PO than the one I used for years because it was on my way to work. For a few weeks, multiple packages of mine never made it to the customer. There was no record that it even left the PO.
When I moved back to my original PO, I never encountered a problem again.

I also wondered whether they knew I had baseball cards in the packages. Since my return address was printed on the label along with my business name, I suspected that was the giveaway. Having Buythatcard on each package might have given them the clue.

I did file multiple complaints with the Postmaster but never heard back.
