Hurricane and Ammo Sales at Walmart

[LTCcarrier]

So I am in the direct path of Hurricane Irma. The stores are completely out of almost anything. My neighbor just came back from Walmart and found that they have a sign on their glass ammo cabinet that they are not selling any ammo at this time even though they have ammo. I am not sure why this would be the case. I have read that Walmart has done this in the past when a government emergency is declared. Obviously no government restriction is on Walmart to cease ammunition sales and they are doing this on their own.
