Just an FYI:
I was curious and went into the local Walmart and Sams club yesterday. All the shelves (where I live at least) are stocked full. Plenty of canned goods. Sams club has large bags of rice, entire pallets full, for about $12.99 each. Lots of bulk canned chicken. No panic here. I do live in a state with confirmed cases.
BUT - I did notice that at the local Walmart, Clorox and Lysol wipes were being pushed to the front displays and people were generally getting a pack or two. No panic buying though.
I grabbed a few bulk canned goods (veggies and meat) and some rice. These are things I will naturally eat anyway... so either way I’m OK.
