I'm not sure whether my package was originally sent and lost, or not, however after contacting Adam & Russell, my package was posted - and I received it yesterday. So if you haven't received anything (recent postal advice or the cards), I would recommend e-mailing Adam!
The lack of communication by Adam/CCC was/is spooking people who paid for something they haven't received (yet). I'm not convinced that this was handled well at all, but it can at least be resolved.
I, and I'm sure many others amongst us, will been keenly monitoring the delivery of the Americana decks.....
