And before long, you have your own little corner convenience store in your home… except it only has the things you want/need.
Here’s an example: let’s say you eat beans 2 times a week. You buy your groceries twice a month. Without using FIFO, you usually buy 4 cans of beans every trip to the store. So you never have more than 4 cans in your home.
With FIFO, you still eat the same (4 cans in 2 weeks), but you buy 6 cans of beans each trip to the store. (It’s less than a couple dollars extra.) At the end of 2 weeks, you buy 6 more, stocking those behind the 2 extra you didn’t eat.
When you eat beans, you take out the first-stocked, oldest cans in the front. And as you repeat this, you add to your extra supplies. Just think, in 4 trips to the store, you’ve built up an extra 8 cans… enough for 2 weeks. Powerful, right?
Oh, you hate beans? Okay, adapt this to whatever non-perishable food item you’d eat.
And if life throws you a curveball (an unexpected expense comes up) and you can’t pay for the extras? No problem. Just eat from your already-stocked-at-home extras until you can start FIFO-ing again.
