I buy my tp in mass quantities anyway simply because that way I don’t forget and we never run low. I worked in sales for a chemical company that did commercial bathroom products too about 30 years ago. I got used to buying a case of tp at a time then. Now I make 1 run and buy at least 10 double roll 12 packs at a time. lol
I find the key is to put one pack of TP somewhere out-of-the-way That way, if we go to get the next one, and we find out we stupidly used the last one without re-ordering, we still have our emergency supply, and if we are not smart enough to order when we touch THAT one, we deserve what we get.
But I’m also ordering one of those ‘bidet’ things, I’ve heard good things about using a bidet anyway, and it would resolve the “out of toilet paper” issue. Heck, some countries that’s all they use, these bidet things.
