My neighbor just bought 15 cases of canning jars and spent (he said) about $450.00 on pressure cookers and other assorted canning equipment. He is urging me to buy similar supplies before there are a 'stampede' and there is none left to buy.
I don't know.
We're already in a rural area and I have everything needed to grow my own food.
You only need the pressure cooker if you are canning meats or eggs. Fruits and vegies can well with an ordinary porcelain cauldron. The lids, rings, and jars are definately a smart buy, unless your place is in a warm climate. We definately are looking at 3 or 4 years of sharply declining temps.
