I have found that to be the case too. Even though customers are limited as to how many rolls they can but, the supplies are really low.
One would think the pandemic is gastrointestinal, rather than respiratory, based upon the run on toilet paper.
I have bad allergies, and blow my nose many times per day, all year. Usually, I don’t know whether I’ve got a cold or the cats, birds or tulip trees are just getting to me - it’s all the same in terms of symptoms and paper usage.
I’ve learned that it’s cheaper to use toilet paper than any other paper product, for this application. I suspect that I’m not the only one in this position.
(Apologies for TMI.)
The larger stores such a Target, Aldi, or large chain grocery only sell name brand or their store brand, that involves extra time to wrap them with their own logo and branding.
A local smaller chain has been able to keep a steady supply of TP most days by by taking what ever their distributor has on hand. Recently they have sold “commercial” TP that is commonly used by hotels, schools, etc. by the roll.
