has anyone overnighted cash and had it get to its destination city, and the tracking info stops. I tracked it and it moves right up to its destination city says it arrived at po, and then it stops. I have sent money before and usually it tracks that letter has arrived at po and then within 10 minutes it says available for pick-up or out for delivery not just arrived at po. think this is something to worry about??? it hasent been 24 hour yet, it states that letter arrived at po at 834 western time zone and that's it.
