I got this directly from a Walmart Assistant Manager. He told me about it because of my position as an Emergency Responder.
"The food shortages are already happening across the board. The way Walmart, the media, and the GOVERNMENT are hiding this fact, is that one week, stores in region A will have bare shelves, next week, region B has bare shelves, next week region C has bare shelves. They are "rotating" this around the country, so that no one area Walmart runs out of food completely. They are only going to be able to keep this deception going for so long before the shortfall grows to the point where this can no longer be kept under wraps! It is WHEN, not if...."
DO what TJ is saying. STACK IT TO THE RAFTERS!
