I have recieved about 4 different shipments of misc gear through the mail in the last 2 mos with no problem. Now I have a card that was left in the mailbox saying I have to sign for something and pick it up at the post office. It is either my clen or test e. the only 2 things I ordered and havent recieved yet. I am a little concerned that I will get there and have somone there to bust me. All the other shipments I recieved I didn't have to do anything like this. What I am asking is: Is this common or should I be concerned.
