I've never had any trouble with USPS until recently (if it could be considered trouble). I had four relatively heavy boxes sent from the US by Priority Mail which contain model steam engine castings. They were all sent at the same time and place (end of July) however I received two boxes two weeks ago, one yesterday and as yet the last box is yet to appear. Tracking showed a smooth flow of information right up till delivery for the first two boxes received, the box I received yesterday showed it still on its way and the box I have yet to receive says it is in Australia. Another item I am still waiting on from the US was sent a month ago by 1st class international mail (has a tracking number) which says it left the US and that's it. I'm very confused but it looks like everything will be turn up in the end
