This will likely be the last news we post about "The Box"; we've already posted as much news about it as we can.
People have started receiving a postcard from Warner Bros explaining that there's a delay in the shipment, and that the box should arrive on Feb 28 (that's an approx date). E.G. Gammon was kind enough to send us a scan of the postcard:

There's a toll free number to call to check the status of your box, but please do not call that number until Friday as your postcard is likely in the mail. The number is 866-488-4640. Unfortunately some people have reported their envelope was returned with the words "inventory exhausted" on the outside. If you haven't sent away for the box then it looks like you're outta luck, at least for now.
Thanks to the E.G., and the other 40 people that emailed us to say they received the postcard.
