They REALLY do a bad job pushing prime now. People in my building had no idea they could have amazon products delivered in an hour and at no extra charge besides an (optional) tip. They use the same drivers to deliver some packages from the site as well.

I guess many people outside the US, like me, are discovering this. Which is understandable, given they have no reason to market this to me.

Their marketing people are doing fine. This service isn't available everywhere, and when it was made available in my city, my local network quickly learned about it and started using it.
