Might need to try contacting a janitorial supply or other commercial warehouse. I think I've seen it from a Grainger catalog or website. It might be 1 ply and scratchy on huge rolls but it's better than a newspaper.
I have not been to the store since early March, before shortages. So I don't know nuthin'. But seems with all the businesses closed their TP could be sold/donated/scavenged. Locally, in Texas, restaurants are now allowed to sell groceries, I wonder if they couldn't obtain that commercial TP from the same suppliers that supply their business?
Don't know. Just noodling.
People and businessess need to think outside the box, or the TP packaging, whichever...
We’re fine in the paper goods department since we usually buy paper goods once every three months anyway. Often order from Azure Standard and they deliver over most of the US. But others could try those places.
