I agree with the others - why go through the expense and risk of canning when you’ve still got Sam’s Club well-stocked. By a good supply there (as I’ve done), a bunch of rice and/or noodles, and you’re pretty much set for months, or even years if you want to go that far.
If we ever get to the point where home-canning is the only option left (i.e., a year or two into a crisis where there’s no food), I’m not sure I’d want to stick around to see the social nightmare associated with that.
