If you are going to buy water, buy them by the gallon, no fees. At Safeway I use the "Just for You" deals. I get a gal. for $1.00.
If your family drink milk, buy them by the gal. and fill the empty containers with water.
I also fill up other large containers that are not suitable for drinking with water and label them "non drinking water."
Even if you can't drink the water, they still have uses.
Just as Haoleb said, canned food can still be good well past the expiration date. Stock up on the cheapies, pork and beans, spam, treet, sardines, progresso soup, campbells, chili, etc.
And don't forget rice, oil, and shoyu.
Many countries eat just boiled rice or fried rice with shoyu.
White rice. Brown rice has natural oils and won't store for long.
Spam, spam, spam, spam, spam, and it's cousins goes with almost anything, sub spam for pork. Actually I think it is pork.
Almost everyone is talking about an economic reset world wide.
It is coming and it is going to happen.
It will be a brutal reset.
From some Christian projections, it actually is very dire for America.
Still, it is better to prep, then not to prep at all.
Always call on Jesus and ask for mercy.
When the final shtf, not even the angels will be spared, and that is saying something.
