I talked to a lady this morning that works there and they said they receive the shipments late at night but are instructed not to put it out on the shelves until 7am. She didn't know why?
I figure that is so that everyone who works there and their cousin can get their pickings before it makes it to the floor.
Not likely. Back when dinosaurs roamed the earth I worked at similar big box stores. They would routinely get shipments at night. It wouldn't be put out onto the floor until the next day or two or not at all (just routed to a different sectionin back corresponding to that department). Different crews.
