We buy them when we can find a good deal on them $.50 or less per jar. That means tag color counts at Goodwill, and end of season at all regular places, whenever Mardens has a deal that brings the price in line with what us cheapos will pay, have had more than a couple given to us. Tend to stay with the pint/quart ones, but have a few dozen half pints. You wood scroungers know the scrounge game it works for jars as well. I guess I got savemoney restarted on canning, I think he has a little problem going overboard when it comes to things he can eat. Moderation, everything in moderation even hoarding heating fuel ..... bear now runs for cover.
Found a hidden drawer on an old table in our basement last fall. This is from a canning book that was found in the drawer.
