Wal-Mart's success in the world is beyond doubt, and its slogan of "parity every day" has been deeply rooted in people's hearts. When it comes to Wal-Mart, one sentence is inevitable: frugality. Why so thrifty? Wal-Mart's answer is: We cherish every penny. We have to prove the value of our existence to our customers, that is to say, in addition to high-quality goods and services, we must also help customers save money. Every dollar that Wal-Mart wastes is actually for customers to spend another dollar. And for every dollar you save for your customers, you are one step ahead of your competitors.
When customers think of Wal-Mart, they will think of low prices and satisfactory promises. They can say with great certainty that they can't find a lower price than this. If they don't like what they bought, they can take it back and exchange it. These are the reasons why Wal-Mart doesn't like sales promotion.
