Final answer:
The statement pertains to business sales strategy, encouraging sales personnel to inform customers about additional items earlier in sales interactions to enhance customer service and potentially boost sales.
Step-by-step explanation:
The instruction 'do not wait until the end of the sale to mention the additional items' can be associated with sales strategy and customer service in a business context. This advice suggests that sales personnel should inform customers about additional items or products earlier in the sales process rather than at the very end. By doing so, customers may perceive this information as helpful and customer-oriented service rather than a last-minute sales pitch, which can enhance the shopping experience and potentially increase the sales volume. For successful implementation, staff training on upselling techniques and understanding the product range is important. Staff should be encouraged to share information about products that complement the main purchase in a way that adds value to the customer's shopping experience. This approach is not merely about increasing the transaction value but about building a rapport with the customer by being attentive and responsive to their needs throughout the sales process.
