Another suggestion for consumers is to buy generic (普通的) items instead of famous brands. Generic items in supermarkets come in plain packages. These products are cheaper because manufacturers don't spend much money on packing or advertising. The quality, however, is usually identical to 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 advertisements 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.
