Report: There are smells that encourage to buying?

Many people thing that there are smells that encourage to buying. Some shops have a cetain smells that attract some people to enter in shop and it's probable that they buy something.
I informed about the shops where more people buy and after I questioned why. 70% of people told me that their favourite shop is Hollister, Double Angetn and Natura. Cassually there are the stores with a more particular smell than others.
When I quiestioned why, the pople told me that the smells is one thing that attract them, therefore they enter and like this shop. The other 30% of people, didn't enter in their favourite shop for smell.
Finally, it's true that there are smells that encurage to buying, because the smell attract people, therefore this people already interested for this shop, and if it like them, they have a one more client.
