Has anyone found a cheap source for canning jars? We pick wild Blackberries in the back of the orchard and make ~70 half-pint jars of jam for Thanksgiving and Christmas presents. But with my adult kids giving jars to their friends we don't get many jars back.
I used to find plenty of jars cheap, in thrift stores. One of the dozen-jar cartons I still use has a $2.29 price tag on it. Those bargains don't exist any more. I paid $37, $1.54 per jar, best price I could find, for two dozen jars from Amazon last year. There must be a better way! What are other people doing?
