Although it maybe a hit or miss situation, you might want to try checking the 2nd hand stores (goodwill, restore, etc.). There have been times when I went there and found anywhere from 1 or 2 to several boxes of rings/lids & even boxes of new jars. Another way my mother/grandmothers used to get by / make do, was to use any jar with that pop up button(?) on the lid (i.e. pickle/salsa/etc. jars). Just be sure if you use the old pickle jars that you always check the lid for that button(?), won't work without according to my mother/grandmothers. Good luck!
