It's tracked the whole way, and only specific people can deliver registered mail as well. That's why it takes longer, but you almost never lose registered mail.
I get it. Definitely a nice thing to be assured of getting your stuff. That said I've had it take over a month to get packages back from PCGS. I don't care how safe Registered Mail is, a month is just ridiculous. FFS we can blast cars into space but we can't get a package coast to coast in under a month?
Jupityr...I agree...a month is ridiculous....that's if your lucky...I had a package from Florida to NYC take about 6 weeks to arrive after getting STUCK in the same distribution center for 3 weeks without moving at all. And this was only 20 blocks away from my post office!
