In this example, the 20-ounce package is the best buy because it costs less per ounce. Remember, the larger package is not always the best buy. It pays to know the unit price. In this example, the unit price shows that the corn flakes from the bulk food section are the better buy. When you know the unit price, you can compare similar products of different sizes.
Many states require supermarkets to mark the unit price on the shelves or the price tags.
Other states may require that the information given be correct and easy to understand. If you find that a unit price label or tag is missing or is incorrect, report it to the store manager immediately. Look for unit price labels on shelves or signs near the item. Compare the unit prices of similar products to find the best buy. If the unit price is incorrect or missing, report it to the store manager.
