You won’t keep consuming the exact thing forever, you don’t have plenty of space, even non-perishables can be damaged or degrade in long-term storage, and you don’t want to expend organizational and indexing capacity on something you can just buy later.
For personal-use commodities, the optimal amount is generally whatever unit Costco offers, or the duration of your cost/convenience indifference point for thinking about it. I know of zero cases where that’s more than a year for me, and of zero where it’s more than 3 years for anyone I talk with.
Actually, I may have over a years’ worth of some light bulbs and some battery sizes. It’s insane to propose “lifetime”, though—these things will get somewhat better or cheaper (relative to my income) over time, and I can’t really predict any changes in size or preference changes over more than a few years.
I’d love to see the calculation / estimate of savings for some things you prefer to pre-pay and then store at your cost and risk for more than a few years, rather than waiting to buy closer to when needed.
