Food is still relatively cheap... Not that you guys don't know this but if you haven't get 5 gallon buckets and get a grain mill and enough rice and grain (flour only really lasts about six months, even under optimal conditions) for a couple of years. Get rabbits and chickens NOW if you didn't already last year. If you need any recommendations on this stuff feel free to DM me.
Agreed on alternate currency as well... It's not unlikely they will push CBDCs and phase out the physical dollar soon. It's likely they'll do this after the "Cyber Pandemic" to make our money "safer".
Dollar Tree has many name brands of canned food, Green Giant, Chef Boy-ar-dee (phonetic spelling of "Boiardi"), Campbell's, and so on. Don't get their Cojack brand dry beans, they're not fit to eat.
There is also Aldi, but be warned, some Aldi stuff --- almost everything they sell is private label --- is very, very good, some of it is just okay, and some of it is absolute garbage. Depends on the item. You just have to take a chance, and then see if you like it. Lidl is similar. They are basically German grocery stores adapted to American tastes. Makes me feel like I'm back shopping in Germany or Poland, and their checkout lines move blazingly fast. Don't let a long line discourage you, the wait is never long. And you do have to bag your own groceries (so take bags with you) and, for Aldi, don't forget that quarter for the shopping cart, you get it back when you leave. Walmart's prices are right, but their grocery aisles (so I've found) are shambolic, crucial items will be missing, and nothing is where you'd expect it to be.
I'd like to keep chickens, and it's legal out here in the unincorporated county, but our HOA would have issues with that, and it gets pretty hot here about seven months out of the year, so it could get fragrant in such a small space.
