Step-by-step explanation:
Factors such as BidBuy's feedback rating system that are valuable to the company's customers but not useful on other online auction sites are examples of customer-switching costs. Customer-switching costs refer to the costs or inconveniences that customers may face when switching from one product or service to another. In this case, BidBuy's feedback rating system creates a barrier for customers to switch to other auction sites because they would lose the benefits of the system, such as trust and reputation.
