Why bother opening post office boxes in the first place when there are plenty of other much safer ways of organizing drop arrangements. You need 100 points of ID for a PO box for starters and the general consensus of opinion is mail addressed to PO boxes comes in for some extra scrutiny. If I were ordering 100gs at a time I would want ZERO link to be between me and the drop and that includes having used some dodgy fake ID to open a PO box only adding to the possible list of charges. And please, no one go posting go to set up a safe drop here!! if the OP doesn't already know it's not hard to find out.
