Final answer:
The best way to close the sale is to agree and finalize it with the customer's chosen band, as this method respects the customer's decision and avoids complicating the sale.
Step-by-step explanation:
The best way for the salesperson to close the sale when a customer has tried on a watch and inquired about changing the band is c) Agree and proceed to finalize the sale with the chosen band. This approach is direct and responsive to the customer's displayed interest and decision. Offering a discount (option a) might be unnecessary if the customer is already satisfied with their choice, and encouraging them to consider more options (option b) or suggesting other watch styles (option d) can lead to decision fatigue or the customer feeling overwhelmed and potentially backing out of the sale. Instead, the salesperson should seize the opportunity to confirm the customer's choice and facilitate the purchase efficiently, enhancing customer satisfaction and making the shopping experience pleasant and affirming.
