It was reported in the Sunday Times on 3 March 2013 that shopping malls in Singapore smell of different scent. Shopping mall concocts their own unique scent so as to allow shoppers to associate different scent with different shopping malls.
For instance, Ion Orchard, one of the shopping malls along Orchard Road, used the scent of natural herbs, fruits and flowers. The spending on these scent in shopping malls ranges from a few hundred dollars to $10,000 a month.
The scent used should be mild and not too overpowering, otherwise it would certainly scare away potential shoppers. If the shopping mall could concoct scent using herbs and spices that could trigger shoppers to buy more, that would make the bosses of the retail outlets in the shopping mall very happy indeed.
Alternatively, in order to reduce spending on scent creation, why not put pandan plants in and around the shopping mall? Pandan leaves release fragrant smell as well. I have visited a farm which plants pandan at its entrance and the smell of the pandan leaves were so lovely that it lured me to walk inside the farm to explore it further while enjoying the fragrant scent at the same time.
