Boy, I didn't realize that toilet paper is such a coveted item. Tried to order some this weekend with my grocery store delivery, no dice. Waited to get some today, store shelf empty. Called one store, nope. Called another store, got lucky. However, I only bought one package of 12. The clerk asked me if I wanted more. I hope that I didn't make a crucial error. Although, I am sure cloth rags and frequent showers will work. Or is running water going to be in short supply soon, too? How long, exactly, are people expecting to be holed up? We only have like 33 presumptive cases in the state that I am in at the moment, and I live in a rather large state.(area wise)
There will be about 10K cases in the US in a week or so. 100K in a month, 1M in 3 months, unless the US government steps in and shows some backbone, close the borders, suspend schools, people gatherings, airports, public transportation and pour money into the development of coronavirus vaccines.
I would buy a year's supply if I were you. You live close to water sources or have a hand pump, don't you?
WHY hoard toilet paper? It's from Canada. I can't imagine there would be actual shortages of trucks bringing it into the US.
On the other hand, there are a great many things from China that may be in short supply.
