A year ago we compiled a price comparison for dry beans. We recorded prices at six local sources including Aldi, the Bishop's Storehouse, Giant Eagle, Kroger, Meijer, and Wal-Mart.
The Bishop's Storehouse sells only black beans, Great Northern, and pinto beans, but in all three cases, buying 25 pounds of beans cost much less, sometimes less than half as much, as if purchased by the pound at a local grocery store. The next least expensive store, generally, was Wal-Mart.
If your budget is limited, when you choose to buy dry beans, be sure to compare prices at the stores where you frequently shop.
