Bread-Bakers v096.n009.2

   I am looking for a mailorder source of transparent airtight containers
that will hold 5 pounds of flour or a little more. 
  The King Arthur catalog has some but they are about $15 bucks apiece and we
need to buy several. 
  Right now, our shelf has a bunch of makeshift containers, including some
leaky plastic bags and I think it is time to establish some order and improve
the appearance.
  What do you folks use and where did you get them?
TIA
