How to be a smart consumer

As consumers, we must be rational and not be attracted by some discount activities of merchants. What looks expensive, in fact, he just takes advantage of a consumer's psychology and thinks that expensive is good.

When you buy something, you must shop around. If you buy it online, it is much cheaper than a physical store. I bought most of my things from the Internet except vegetables. For example, a toothbrush in a store, 10 yuan. If I can't buy 10 yuan online, I can buy four toothbrushes.

Buying things is not necessarily expensive, as long as there are many people buying them online, you can choose the ones with high sales. Don't buy things you don't need, even if they are discounted again. If you buy it and leave it there, it's a waste of money.
