What purchase strategy drastically lowers the cost per serving for dry grains like rice?

Purchasing in large, bulk bags (10 or 20-pound increments)

To achieve the absolute cheapest price point for staples like rice, the key strategy involves buying in bulk quantities, specifically mentioning 10 or 20-pound bags. This bulk purchasing significantly decreases the cost associated with packaging, distribution, and retail markup per unit weight. When comparing this method against buying smaller packages or instant varieties, the savings per cup serving can exceed 80 percent. This initial investment in bulk dry goods is fundamental for achieving long-term success when adhering to extremely tight budgets, as the unit cost plummets when acquired in large increments.
