Abstract: Various embodiments are directed to a customer computer device for facilitating the purchase of products comprising at least one processor and operatively associated memory. The device may capture a product identifier from an instance of a product. The product identifier may indicate a first instance of the product. The device may also transmit the product identifier to a service provider system and receive from the service provider system a rebated sales price for the first instance of the product. The rebated sales price may reflect an invoice price of the product, a deduction to the invoice price, and at least one rebate offered by the manufacturer of the product. Additionally, the device may provide the rebated sales price to a customer via a graphical user interface.

Abstract: The sales of automobiles are promoted by providing to a customer a portable media player including a user interface permitting the customer to selectively play one or more walkaround instruction files so that the customer may engage in one or more guided walkaround examinations of vehicles without the presence of a salesperson. The user interface further permits the customer to send a wireless signal requesting salesperson assistance. In response to such a signal, the salesperson engages in face-to-face interaction with the customer. The training of sales personnel may be enhanced by the same or similar portable media player as is provided to the customer, allowing the sales personnel to selectively play one or more sales training files. The media player may signal a base computer of the completion of selected training files, allowing automobile dealership management to track sales training.
