What type of sales aid does Harper use when selling computers to prospective buyers?

Harper's use of electronic materials as a sales aid when selling computers is appropriate for several reasons. In the context of technology sales, electronic materials, such as presentations, videos, and interactive demos, can effectively showcase the features and benefits of a product like a computer. These materials are often more engaging than static alternatives, allowing prospects to see the product in action, understand its capabilities, and visualize how it can meet their specific needs.

Additionally, electronic sales aids can be easily updated to reflect the most current information, specifications, and promotions, ensuring that Harper is providing the most relevant and persuasive content. The interactivity of electronic aids, such as touchscreens or virtual demonstrations, can further enhance the customer's experience by offering a more personalized and informative approach to the sales process.

This choice aligns well with the nature of the product being sold, as technology buyers typically appreciate detailed, dynamic, and informative presentations that can help them make informed decisions.
