Here in the US it costs $1.20 to send a postcard to international destinations.
Surely, part of that cost funds the USPS to somehow get the card on the ground in the destination country.
But from there, the postal service for the destination country takes control, I assume. Does anyone know how that hand off works? And how it’s decided what we pay other countries to make the final delivery (if in fact that’s how it works)?
Just curious if anyone knows about this. I figure my broad assumptions are mostly right, but interested to learn more.
