When formulating product pricing strategies, companies should follow the principles of fairness, transparency and integrity in order to establish long-term stable customer relationships. Although opaque pricing strategies and complex consumer terms may increase profits in the short term, in the long run, this approach will damage the reputation of the company, lead to customer loss, and may even face legal risks. We recommend that companies increase profits by providing high-quality products and services, optimizing cost structures, innovating marketing strategies and other legitimate means, so that they can not only win the trust of consumers, but also maintain sustainable development in a competitive market.
