Walmart has some useful low-cost staples and Rollbacks right now, including pantry basics, produce, meat, frozen vegetables, and baking ingredients. The better buys are foods that can cover several meals or replace something noticeably more expensive. Prices are accurate at the time of publishing but may vary by store or sell out quickly. They take only a few minutes to cook, so saving money does not mean adding much work to the morning.
