Just as a data point -
Platinum Kit showed up in my mailbox a few days ago, about a month after I qualified. Status tracker changed to "pending" a couple of weeks ago (and remains so)
I'm based in Japan, and it was sent from a Japanese address.
The tracker also showed "shipped" for my Silver and Gold kits at some point in the past 6 months, but those two envelopes are nowhere to be seen.
