The cheapest place to buy mason jars is a flea market or garage sale. But make
sure they don't try to pawn off mayonaise jars on you! Get modern Ball and
Kerr and Atlas (there are a few others) jars that have a nice thick sealing
surface at the top.
You might find a Presto canner at Wal-mart, or your local big hardware (not
building supply) store.

bob
