And, don't forget your calculator. Everything looks good when you're hungry - and that makes it hard to stick to your list. Also avoid shopping when you're tired or in a hurry. Follow your shopping list so you won't spend more money than you have budgeted. But, be flexible and be ready to substitute a similar food that's specially priced.
Many stores list the unit price with the product price on the display shelf.
Its NOT a bargain if you end up throwing out an item because your family did not like it or it spoiled before it was used. Never purchase a can that is dented or bulged. It depends on the product and how it fits your plan. Before buying the largest size, decide how and when you will use the food and how well it will keep when you don't use it immediately. The versatility of single-serving items can make them a better purchase for smaller families or households.
