You’re shopping for a high-priced product, but have limited money. How to make the best use of your money? Here are some steps you can take to become a smart shopper.

Step 1. Before buying a high-cost product, think about:

·why you are buying the product

·how often and when you will use the product

·what the main use of the product is

·why you need this product now, not later

Step 2. To choose the best product, you need to research and find out:

·what companies make the product

·the differences in each company’s product

·what others say about the product

It can be very helpful to know what other people say about a product you want to buy. Product reviews often describe problems. Reviews also tell how people use the product. List product information so that you can refer to it before you decide to buy

Step 3. To find the best price for the product you want to buy, you need to compare:

·prices of the product

·brand(商标) names and store names

·places to buy your product (in stores, online, etc.)

·product labels(标签) and information

Step 4. As you get ready to buy, search your local newspaper and the Internet for special offers. Many sales are offered around holidays or at the end of a season. Wait to see if there will be a holiday or end-of-season sale before you buy. Check to see if you can get a lower price for the product you want to buy.

These steps will help you become a smart shopper. If you follow them, you should get the best deal. Remember, the more you know, the less someone can take advantage of you.
