As inflation continues to drive up grocery bills worldwide, price tags change by the day. In response, some retailers have replaced paper tags with digital pricing displays to reflect constant fluctuations in real time. Amid growing anxiety around fluctuating prices, German discount supermarket chain Penny set out to offer a sense of price stability to the concerned consumers. The brand launched “Price Packs”—a line of best-selling private-label products with the price printed directly on the packaging. By making the price part of the product itself, Penny reassured shoppers that the price would remain fixed, driving the increase in sales.
