I waited 6 weeks once for a source to mail my funds back. He gave me the tracking no. and it showed being dropped off at the post office. Well...apparently it got lost because it arrived exactly 6 weeks later. We both were sweating. So, the usps does make mistakes. If you have a tracking number that shows up as being dropped off at the post office, it's out of your sources hands. But if he tells you he is shipping and it takes a long time, he probably didn't ship.
