I know, it always amazes me what they let through. The most common thing 'wrong' with Specials is that the accepting PO hasn't pointed out to the sender that they havent included a return address marked on their envelope/package. Youd think someone paying for the Specials service would at want it returned if it ends up not called for/not found/unknown etc.
