U.S. customs probably won't be so bad about it, but I wouldn't want to head to the UK or some country like that with a quantity that was obviously in excess of personal needs. The EPL in particular has been ogre-like about that (like the NFL would be if more countries cared about them). Also team England...if those guys had focused half as much on fielding a decent team as they do on fighting unofficial merchandise then maybe they would have won a World Cup more recently than 1966.
