According to this article retailers are increasingly using scent in their stores. A Canadian company called Mood Media has been working with 20,000 different stores in Britain to help boost their sales. They use a combination of techniques including sound and visual media, with the latest trend being the use of scent. Popular scents include Lotus Flower and Enchanted Apple. The company has already created scents for Habitat, Timberland and Guest. The perfumes are pumped out through the air conditioning units and are aimed at making the customer stay in the store longer. The smells have to be subtle so that the customers don’t notice it except on a subconscious level.
