Customer feedback is heavily sought after in all industries, and retail is in a unique position in that every transaction is an important data point. In fact, the customer is already telling you what they want to buy. You just have to respond by looking at the data points and implementing the right actions as if they filled out a survey.
Your sales data is a treasure trove of information that you can use to improve your business. If you leverage it to inform your media at the dispenser and other shopper marketing strategies, the historical sales data you already have can help you promote the right products at the right times, increasing sales and overall profitability.
