Well I went down to the Post Office to retrieve the other two packages and surprise surprise they were not there. Supposedly that tracking message means they are ready to be picked up by the route mail person rather than me, And they may or may not get delivered today since they "are running behind".
Yesterday went I went there I was told my route was "split delivery" - which I think means that 1/2 of the route gets serviced one day and the other the next.
