At least in my state, all necessary stores like Walmart and groceries are open. I've ordered through Amazon a half-dozen times since the shutdown. Even our restaurants are open but no dine-in. It's pickup or drive-thru only.
I personally think the government has been / is behind the hoarding of / shortages of toilet paper. There is still note to be found on Wal Mart shelves....it's all a govt ploy. There is no TP to be had by consumers to help businesses open back up:
Gotta go to the bathroom? Then you HAVE to go to a restaurant....and businesses opening back up will entice patrons to come in and get 1 roll of TP per shopper as a free gift...
I'm not much into conspiracy theories, however you brought up a point I was discussing with my father a few weeks ago about toilet paper.
He stated he basically grew up without toilet paper, since back in the 40's, there were a lot of poor people. I didn't ask him to elaborate.

In any case, when I was working, one of our customers (Granger) supplied many businesses. While I have enough toilet paper for the coming weeks, if I couldn't find it anywhere, I would go to Granger and get it from them. Mind you, they are very expensive, but at least I'd have it.
I figure with all the businesses closed up, and the ones open probably have a skeleton crew, Granger would have ample supply of it since businesses were not ordering much.
