Final answer:
Consumer prices can be unfair if they involve manipulative or deceptive tactics, but not all price variations are necessarily unfair. Legitimate factors like production costs and market competition can also influence prices.
Step-by-step explanation:
Consumer prices can be considered unfair if they violate the principles of honesty and fair dealing in the buyer-seller relationship. While prices can naturally fluctuate due to supply and demand, unfair pricing practices can occur when businesses engage in manipulative tactics or deceive consumers. For example, price gouging during times of crisis or misleading pricing strategies that trick consumers into paying more than they should can be considered unfair. However, it's important to note that not all variations in prices are necessarily unfair; legitimate factors such as production costs, market competition, and economic conditions can also influence prices.
