sounds fishy but pappa is right - make sure the house is CLEAN - your computer is incrypted - most people gett fried because when the controlled delivery happens they get busted with all the stuff that is in there place which is usually quite a bit more than what came in the mail - if there is nothing in the house, it is a lot harder to prove that you did order the goods.

the reference to usps is probably the idea that using them to commit a crime (sale of controlled substance) represents a crime in itself - but even if that were applicable, that would apply to the seller not the buyer.
