OK, this is vaguely hopeful:
Your item was processed through and left our OPA LOCKA, FL 33054 facility on September 24, 2010. The item is currently in transit to the destination. Information, if available, is updated periodically throughout the day. Please check again later.
I just hope the “destination” is me. Nothing in today's mail, so I guess I'll find out tomorrow…
Meanwhile my package continues its Florida vacation.
In light of some of the entertaining (thank you!) comments on previous postings, I should mention that this is only the second time in at least ten years that something ordered online hasn't turned up more or less when it should. Admittedly, the bulk of those purchases shipped UPS or FedEx, but some appreciable fraction, including purchases from abroad, came USPS.
