Multi-sensorial shopping
Touch and taste often coincide, but smell can also add a dimension to the sense of touch. Make sure that the scent in your store matches the experience of touching the products (e.g., the scent and the material are congruent), so that the product that is touched by the customer is evaluated more positively. For instance, a “manly” scent may be diffused in a rough and rugged interior to enforce the masculine experience.
