For example, in many shopper categories these can consist of seasonal packaging, sweepstakes-type flashed packaging or unique collectables. If consumers are doing stock-ups, offering bonus packaging, time-limited offers highlighted on the packaging, or multiple purchase offers help to drive purchase behaviour. This type of incentive provides added value in the form of convenience, and it directs the consumer away from potentially buying a competing brand. Package design for fill-ins and special purchases should reflect strong shelf impact, stronger end-benefit messaging, or reinforce a lifestyle benefit that talks to the emotional state of the consumer.
