Well, this is an extremely bizarre year thus far. I've gone to the store and seen no meat, so I've been stocking up what I can when I find it. Do you know any ranchers? Befriend them and get on their purchase lists for butchering their livestock- it's more expensive, but meat prices may remain elevated. Dairy- many cheeses can be frozen. Eggs are another thing. Did you know that you can freeze eggs? I have small ziploc containers that will hold 2 and 4 large eggs; I just crack them and scramble the whites and the yolks, and put them in the freezer. I also have 2 gallons of milk in the freezer; freezing it does no harm and upon thawing in the fridge, you just give it a good shake and it's good to go. Toilet paper, of course.
I've also been stocking up on cold meds, allergy meds, stomach meds/antacids.
Comfort foods, snacky stuffs, beverages for cold weather. Soups. Soaps. Good lord, Dawn dishsoap was a rare commodity for a while. Hydrogen peroxide. Isopropyl alcohol. Yeast. Flour and baking supplies. Even if you don;t use some of this stuff, I guarantee that you know someone who does. PET SUPPLIES. Man, Chewy was over a month behind on standing orders back in April and May. Stock up now on kibble or litter or whatever your furry buddy needs. If there's a whiff of COVID, I suspect there will be less hesitation to close everything down again. I SO hope I'm wrong.
Gardening stuff- if you're like us, we've started gardening (along with the entirety of western civilization, it seems) and have run into shortages there, too. As seeds and various soils and fertilizers come back in stock, grab them so you're not hampered early next year in February and March if you start seed indoors.
Holiday stuff. Try and get your holiday gifts and decor/foods/traditional things now- remember how Amazon limited what they would ship immediately? How Walmart was pretty much your only choice for purchases, unless you wanted to count on inconsistent shipping?
I know. It sounds like the sky is falling, right? This is just my list. And what I've seen of how this whole thing was handled has me relying on myself to take care of us, because our "authority figures" are far too busy virtue signalling to actually be stringing together the thoughts of every action resulting in reactions. I'm seeing that these reactions are having ripple effects that will take quite some time to smooth out.
