This document discusses two consumer sales promotion tools: refunds/rebates and premiums. Refunds/rebates allow customers to get money back after purchasing a product by submitting required information via mail, though it takes time to process. Premiums reward existing customers with free or low-cost items for purchases to increase sales and maintain customers. While both can attract and retain customers, refunds/rebates are easier to measure and premiums must target the right customer group to be effective.
