The aim of this research is to study the effect of ambient scents on consumers' responses and in particular the moderating effect of consumer type (hedonic vs utilitarian) and his accompaniment state (accompanied vs single).An experiment was conducted in a real business context (NIKE store), where 400 customers were surveyed. The results indicate that a pleasant ambient scent improves evaluation of store environment, products, quality of services provided, the level of pleasure experienced, the level of stimulation, their intention to revisit the store and customers' spending. However, ambient scents have no effect on the real time spent in the store. Finally, in the presence of an ambient scent, it was found that hedonic customers intend more to revisit the store than utilitarian ones and that accompanied customers tend to spend more and have more fun shopping than single customers.
