[pct-l] Returned Packages

[tom_d_w at hughes.net]

How real is the possibility of the post office returning a package to 
sender if it is not picked up in two weeks?  I am trying to reduce the 
number of trips to the post office that my re-supply person has to make 
and lengthen the bounces of my bounce box.  I would like for my re-
supply person to be able to mail the package I need in a month at the 
same time as the one I need next week.  They would all be Priority flat 
rate.  My worry is that if the later ones arrived too far ahead of me 
that the PO would send them back.  Any advice?

Thanks,
Tom
