The sales of a product increase as the number of people who have used

The sales of a product increase as the number of people who have used it increases. Sampling is a good method to increase the awareness of the products. Therefore, many energy drink manufacturers put stalls around each city they are targeting and distribute free energy drinks as each flavor is launched.

Eventually energy drink manufacturers are forced to keep producing new flavors.
