First, the most intuitive thing is that the event of buying something can be confirmed? Did you get what you paid?
The quality of expensive clothes must be good, and the quality of cheap clothes must be poor. This is not absolute. But many times, the more expensive the clothes we buy, the better the quality and the longer we can wear them.
Second, buy virtual online goods.
Now you can buy online games gold coins, virtual online courses, membership recharge and so on. Gold coins and members can be collected directly, and we can choose cheaper ones. However, if online courses are cheap, they are not necessarily genuine online courses, because the official genuine ones are all at the same price, and the price of the same type is much lower than that of the same type. At this time, we should pay attention to see if what we bought is genuine.
