Depending on the types of smells you smell when shopping you can either spend more or less.

The research done determined that the smell that made your purchase the most was actually oranges! Yes, oranges! When compared to no smell, spenders actually spend about $12 more when they smelled oranges when shopping.

Things could also go the other way as well. When people smelled green tea they actually were apt to spend less (around 6%) when compared to when there was no smell.

The study was conducted in Switzerland at a furniture store.
