Final answer:
The retailer's actions involve implementing a policy to address a customer's frequent large purchases and returns. This strategy is similar to a money-back guarantee used by mail-order and web-based firms.
Step-by-step explanation:
The retailer's actions can be described as implementing a policy to address a customer who regularly makes large purchases and returns everything two weeks later. By requiring intact tags, unworn clothing, and a return within seven days to receive credit, the manager is aiming to discourage the customer's behavior and ensure the company's profitability. This strategy is similar to a money-back guarantee, which is commonly used by mail-order and web-based firms to encourage purchases even without the ability to see or touch the products.
