"Many are losing faith on promotions, but I still believe there’s a place for promotions in grocery retailing, helping to drive footfall and growth. It’s the quality of the promotion that counts, and it also comes down to everything in moderation to avoid overdose. In grocery, 40-60% of the lines are on promotion at any one time, so being able to make better decisions in managing those promotions for your most loyal customers is probably the biggest way to make money these days."
