I had a grandma who kept her money beneath a floorboard under her bed. Maybe I should do the same.
There are no rewards for people who work hard and save their money. They are all saps.
Why? So it can become more worthless by the hour?
Invest it.
Food, Spices, An apparatus that can purify water, Ammo, Weapons (At least a 12 ga. a Kabar knife and a 22 rifle for each family member.) First aide supplies, Junk Silver.
All of the above is going to go up in price so buying now is the same thing as investing. And, it may save your life if the SHTF!
