     Never go into a supermarket hungry! This is a good piece of advice. If you go shopping for food before

lunchtime, you'll probably buy more than you plan to. Unfortunately, however, just this advice isn't enough

for consumers these days. Modern shoppers need an education in how and how not to buy things at the store.

First, you check the weekly newspaper ads. Find out the items that are on sale and decide if you really need

these things. In other words, don't buy anything just because it's cheaper than usual! "New and Improved!"

or "All Natural" on the front of a package influence you. Instead, read the list of ingredients (成分) on the

back. Third, compare prices; that is, you should examine the prices of both different brands and different

sizes of the same brand.

     Another suggestion for consumers is to buy ordinary items instead of famous brands. Ordinary items in

supermarkets come in plain packages. These products are cheaper because producers don't spend much money

on packing or advenising. The quality, however, is usually as good as the quality of well-known name brands.

In the same way, in buying clothes, you can often find high quality and low prices in brands that are not

famous. Shopping in discount clothing stores can help you save a lot of money. Although these stores aren't

very attractive, and they usually do not have individual dressing rooms, not only are the prices low, but you

can often find the same famous brands that you find in high-priced department stores.

     Wise consumers read magazine ads and watch TV commercials,but they do this with one advantage:

knowledge of the psychology behind the ads. In other words, well-informed consumers watch for information

and check for misinformation. They ask themselves questions:Is the advertiser hiding something in small print

at the bottom of the page? Is there any real information in the commercial, or is the advertiser simply showing

an attractive image? With the answers to these questions, consumers can make a wise choice.
