I have kept six months of staples in my pantry for years. Learned this during the lean dollar times of my life. DH and I were fine when the isolated hit and still are as far as food goes. I go once every two weeks to replace what we use. Still have six months of food stuff. Been giving some to my kids but they learned from me, they had a fully stocked pantry to begin with. This keeps us from rushing to buy what others need to buy. I hope everyone keeps a good supply of basics when this settles. No rushing or doing without when another emergency occurs.
