SEALED container that can hold 30lbs of dog food and doesn't cost a mint?

Go to your nearest Lowe's/Menards/Home Depot and purchase 2 big white plastic buckets with lids that contractors use to mix paint, wall compound, etc. They're about 5 gallons in size and 2 ought to hold 30 pounds of food. The lids are excellent to keep other critters out and they have carry handles. They're really inexpensive, too.
