Why do some customers only pay attention to price? Instead of putting service and other important things first?

This is a price-oriented customer, who shifts the customer's attention to price to the quality and service of goods. For example, we can give an example that happens to us or has a great influence to illustrate that besides paying attention to price, quality and service are the things we should pay attention to. Besides paying attention to the price, customers should also pay attention to the characteristics of products. What does he need this product to achieve for him? Solve what! Why else would he buy something like this? In this respect, customers can only pay attention to the price.
