Neat, but I prefer my own method:

1. Have two toothpastes (actually two of everything) 2. When one gets used up, remove the checkmark from my shopping list (just a simple checkmark list on my phone in Google notes) 3. When in the store, buy everything that's not checked on the shopping list

Works all the time, except during the CoVID toilet paper crisis, which made me increase my prepper level to 3 of everything.

My toilet paper routine, which started even before covid, is to buy about 400 rolls of toilet paper from Costco, and then I never even think about buying toilet paper ever again for a couple of years. And then one day it runs out and I realise the infinite toilet paper stash was in fact finite after all. As if that isn't bad enough on its own, I then discover that while inflation has been running at 9% a year for everything else, it was more like 100% a year for toilet roll.

A different class of problem with this technique is when I bought 150 old-style lightbulbs just before they got banned in the UK. At the time, I really hated LED lights because they flickered, and so I could use them in areas I just passed through, but nowhere I sat and spent any time. I still have about 120 of them left because, of course, LED bulb tech has got better and I now only have 2 lights in the house that still use the old bulbs. They don't get much use, one is in the loft and one is in a cupboard.

Just a simple 2-queue. I love this, since it's low friction and your essentials are persistent. No more brain-wracking to remember what the grocery list is missing.
