Eh, I honestly don't think it's a problem either way, the PO box just costs more.... I was just trying to make a point (when i said the thing about the bust at the PO box) before. Both should be safe... If you're busted your busted, i think being booted from school would be the LEAST of your problems at that point, and i know for a fact that - at least at my school and many of my friends' - first time drug offenses are just a slap on the wrist; you don't get booted....
