I have seen posts all over Facebook where people that wanted to make jam or pickles couldn't find jars anywhere. Here, all of the stores are out as well. People who have been stuck at home and gardening for the first time are getting into canning. For a while I couldn't find bread yeast either, and we have been making our own bread for a long time. But, others getting into it...
I have boxes stacked taller than me with empty jars in the barn, because my Granddad spent years gathering up jars from his friends that passed away. If currency ever fails, I plan on trading jars for pizza and sexual favors.
