"Retailers are being forced to rethink their merchandising at the front end as they deploy self-checkout systems," says IHL President Greg Buzek in a press release. "The impulse displays have not caught up to this new technology. By definition these are impulse items – thus they must engage the senses. Retailers such as Meijer and Kroger have adjusted by offering items such as rotisserie chickens and fresh baked breads to rely more on the sense of smell to drive sales rather than simply visuals when trapped in a staffed lane."
