Consider choosing frozen food items when suitable. Frozen corn, peas, fish and many other items are cheaper than their fresh (non-frozen) counterparts because they have a longer shelf life.
Stores have to consider the losses that can be incurred with anything that is perishable, and build that into their profit margins.
You can save hundreds - or even thousands - of dollars a year by shopping at lower-priced food stores.
Shop at stores known for lower prices. This varies by geographical location. Keep in mind, however, that not all products will be cheapest at those stores. For example, Walmart may have the lowest prices on bread, milk, produce and orange juice, but may have some of the highest prices on beer and eggs. Always compare, and when justified, shop at multiple stores, especially if there a located close to one another.
Likewise, convenience stores often charge the highest price.
