Very True, but sometimes there is a disconnect between an order and what goes to the shipping department. No one monitors every transaction, and if the item is a paid in full, authorized CC transaction, the shipping ticket might print to someone only concerned with getting it out the door. Sears notoriously has jacked up computer systems.
It is plausible for an order to be processed, and the shipping dept get the pull and ship request. BUT, now that they have been alerted, any such system gap will be closed.
