shortages everywhere

[papaof2]

If empty shelves at your local stores don't concern you, maybe a look at what the LDS (Mormon) online store has and does not have will change your level of concern.

They once offered an Excel file that let you put in the number of people by age and gave you some useful info about quantities needed for a year or whatever but that's no longer on their public-facing web pages. They do talk about having 3 days/3months/one year of supplies and offer a link to their store. I probably have a copy of of that spreadsheet squirreled back somewhere. If I find it, I'll make it available online.

While you're here, a couple of references for you:

Food for one adult for a year - 2019

LOTS of references on storing all types of foods.

An older Mormon "year of food" spreadsheet - but I suspect the quantities are based on living the farm life:

Some online food storage calculators:

That is a significant drop in both offered and available stock. In years past, they had several pages with most in stock.

If you're waiting for "something" to happen before stocking up, you are being foolish. Get it while you can!
