Paper products—as much as you can store—toilet paper, paper towels, kleenex, napkins.
Cleaning products—whatever you use now buy several more of all of them.
Canned foods—same.
Health and beauty items—go through your medicine cabinet and bathroom cabinet and double, triple up on everything in there.
Clothes you wear a lot (like jeans)—buy lots of them—in Europe they are crazy expensive, could happen here.
Shoes—buy extra pairs of your favorites.
Ditto for underclothes, socks, layers for winter if you live in a cold climate.
Batteries—could be power outages if the Greenies have anything to say about it. Spare flashlights.
Get a battery operated radio and scanner if you don’t have one already—also the battery operated DVD/CD players are cool if you have a collection of those.
Thank you
I would say rechargeable batteries and a solar charger for them.
