The Internet of Things (IoT) technology presents an opportunity for retail groceries to develop an infrastructure that makes physical things such as mobile phone, shopping basket, store shelves, digital display, and, even the product itself smart, allowing real-time interaction with customers both in the physical store and in the virtual store. This study explores how IoT can enhance value in retail grocery choice situations. To analyze IoT’s impact on consumer decisions, we conducted a conjoint experiment where participants purchased fresh salmon in a grocery store. The results demonstrated that compared to static information on price, expiry date, quality, and general offers, real-time information was the most influential factor. Moreover, quality ratings from other customers had the strongest effect, followed by personalized offers based on cart items, real-time expiry dates, and real-time pricing.
