                                             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.
