                                             Smart Shopping for Food. 
The first step in smart food shopping is to prepare a shopping list of the items we need to complete the meals we have planned. This shopping list should also include staple items we need such as salt, sugar, and paper towels.  With a shopping list we can avoid several costly mistakes. We can make certain we get everything we need and avoid extra trips to the store. A shopping list also will help us avoid impulse purchases that will run up our grocery bill. A shopping list also can help us avoid overbuying perishables so that we can eliminate wasteful spoilage. An important part of smart shopping is the choice of a place to shop. Prices and quality do differ much among stores. Prices differences are larger between supermarkets and small convenience stores. These smaller stores are open long hours, but their sales are small, so it results in higher prices. Supermarket shopping can give you some extra savings especially for large orders. Choosing a supermarket may be difficult. Some stores try to draw in shoppers with attractive specials. Other stores advertise “everyday low prices” or “discount prices”. Information included on the labels of food products is strictly controlled by the law. Food shoppers can find most useful and reliable source of information there. Labels provide such important facts as the ingredients and the relative amounts of each that were used, the net weight of the package contents, the name of the processor or distributor, and federal inspection information.
