Abstract: A method and system for advertising and selling products while a customer awaits his turn for service in a wait queue. The invention permits the customer to chose to listen to advertisements while in this wait queue. If he chooses these advertisements, the customer then enters the advertisement queue, where the first gets a summary list of ads. The customer then listens to the advertisements(s) he selects. If the customer decides to buy a product, the customer can choose to register with the on-hold add systems permitting future “one-button” purchases. If not, the customer would then enter credit card and shipping information. While in the advertisement queue, the customer continues to advance in the wait queue. The customer is guaranteed to advance at the same rate as if the customer were in the on-hold queue. The customer can choose to leave the ad queue at any time.
