While you hand-deliver the letter, you could pick up a movers guide at the local post office and give it to them, or they tell them they could do it online ($1.10 fee).

The "10102 USA TODAY WAY" address is on everything. Come on Joe and Co, this is really getting ridiculous! Are you saying you'll go to jail if you update your bad address...

FYI - I sent a first class letter on 11/22 addressed to:

RETURN SERVICE REQUESTED
GENEREX BIOTECHNOLOGY
10102 USA TODAY WAY
MIRAMAR FL 33025-3903

I got my letter back on 12/9 with a yellow NIXIE sticker that says:

RETURN TO SENDER
NOT DELIVERABLE AS ADDRESSED
UNABLE TO FORWARD
