Sugar is another important item. Honey is nice to have too.
If you need canned items/dry goods you can also try the local
Mormon Church...They're Everywhere!
They have a mandate that all members must have a year supply
of food in their homes for emergencies/hard times.
As a result, they do alot of their own canning at
"The Bishop's store house." These things are also spread around.
They will sell to non-members. The prices are quite reasonable, and the quality is really good.
We were able to buy many 50lbs of wheat/rice/beans/oats, etc.
