The correct answer is D .
A successful promotion should create value for all three parties: the retailer , the manufacturer , and the shopper . The CPCM material explains that promotion is “a key driver of incremental sales” and “an important point of differentiation for retailers.” It also states that promotion is reviewed from both a marketing perspective and a promotion/flyer program perspective, including planning, execution, assessment, incrementality, price, ad space, display support, seasonality, competition, ROI, and breakeven.
The retailer benefits through incremental sales, traffic, basket growth, differentiation, and category performance. The manufacturer benefits through increased product movement, brand visibility, trial, and potential share gain. The shopper benefits through value, awareness, savings, and purchase motivation.
Option A is incomplete because the retailer is not the only beneficiary. Option B is incomplete because manufacturers benefit only when the promotion also works in the retail context. Option C is incomplete because shopper value is necessary but not sufficient. A promotion is truly successful when it produces a win for the shopper, retailer, and manufacturer.
