Wal-Mart and 'continuity of government'

Is Wal-Mart working hand-in-hand in preparation for some future disaster?
Guest host Jack Blood, speaking on "The Alex Jones Show" (Jones is in L.A. for the big 9/11 truth event) seems to think so.
A listener to Jones' show wrote in and said they work at Wal-Mart in a Missouri town and said pallets of foodstuffs marked COG (aka Continuity of Government) are being placed in a warehouse until it was totally full. The listener said it's all very secretive and that only top management knows about it.
So, what does the government know? Is this normal preparations just in case? This is kind of troubling. I wonder if the Wal-Mart in my town is doing the same thing. Of course we have an Army base next door.
