What are the common consumerist brainwashing words in life?

I'm confused by verse 38 these two days.

The main shopping software is sold in cu.

This supermarket sells copper coins.

Even pharmacies are engaged in cu sales activities.

It's really hard for everyone to spend.

Merchants package consumption into zi.

I tell you, if you spend this money, you will become better.

I'm telling you, you'll lose money if you don't buy it at this time.

But what is it really like?

Give an example of buying samples.

I used to be a shop assistant, and my boss taught me that if someone bargained for a cheaper price or wiped it off, don't promise and give him 10 yuan a small gift. Because you get less money by pulling Jia down directly, but you get 1 yuan foolishly, and there is no shortage of money to make customers happy. This is the basic common sense of businessmen.

I have listed all the above consumption routines.

Welcome sisters to add.

Let's spend rationally.

Spend the money saved, and resolutely don't be a big head.
