I stocked up on my beloved Cottonelle with Aloe a couple of weeks ago when I was doing prep for a potential quarantine situation (making sure we have enough non perishable food in the pantry) before all the sheep got wise to COV-19.
Not because I'll need it in the event that happens, but because I knew the dummies who had no clue about what was coming we still be dummies when they went to the store and buy up all the toilet paper. And then there wouldn't be any when a person like myself just needed 1 pack for normal supply replenishment.
The biggest part of disaster prep is thinking about how stupid people will react. Thinking about what you actually NEED on hand is the easy part.
Water and toilet paper.
Your utilities aren't going to be turned off and you aren't going to get burrito shits.
