Sales-wave research

one of the methods used in consumer goods market testing. In this type of research consumers who initially try the product at no cost are re-offered the product, or a competitor’s product, at slightly reduced prices. They may be re-offered the product as many as three to five times (sales waves), with the company noting how many customers selected that product again and their reported level of satisfaction. Sales-wave research can be implemented quickly, conducted with a fair amount of security, and carried out without final packaging and advertising.
