Customer perception can be a powerful tool for pricing, yet it also has its challenges and risks for retail sales. For instance, customer perception is subject to change due to changes in customer needs, preferences, expectations, or emotions, or due to changes in the market environment. Thus, retail sales should monitor and measure customer perception regularly and adjust their pricing strategies accordingly. Additionally, customer perception can be influenced by external factors such as social media, online reviews, influencers, or word-of-mouth which can impact the business's reputation and image, as well as the customer trust and loyalty. Consequently, retail sales should manage their online presence and reputation and engage with their customers and stakeholders to build positive relationships and feedback. Furthermore, customer perception can be distorted by cognitive biases such as anchoring, framing, or loss aversion which can affect the customer's judgment and decision making. To avoid misleading or manipulating their customers and ensure fair and transparent pricing practices, retail sales should be aware of these biases and use them ethically and responsibly.
