Learn the prices of foods you buy most often, so you can tell whether a sale is really a bargain. You might even write the prices in a little notebook. Stores sometimes say a food is on “special” without lowering the price. Beware of quantity specials, too. Usually when an item such as pasta or canned soup is on sale for “10 for $10,” you don’t have to buy 10 to get the sale price. You can usually buy as few or as many as you like, and each one will cost a dollar. The sign should tell you if fewer would be priced differently. And if you’re not sure, ask a store employee. The more you know, the more you can save.
