So I ordered some U-47700 while it was still legal from a clearnet site, but while on its way here, it has since been scheduled. Apparently they tried to deliver today, but I wasn't home, so I got a card in the mailbox saying I need to pick up a package from the post office. What do?
Take your card, proceed to the Post Office, and receive your package.
They don't know what's in the box, and they sure as hell don't know it contains a recently scheduled drug.
