However, looking at it as marketing, it is a tool that allows the consumer to experiment and decide if they want to pay full price for it, that is, it is used to bring the item closer to the customer.
It should be noted that, initially, the company that started with the distribution of the coupons was Coca-Cola, as a method for Americans to obtain an image of the product more oriented towards a refreshing drink. With this, the success it achieved around the United States was tremendous, therefore, over the years, it became known at a global level, becoming one of the essential products of the world basket. This was imitated by other companies that manufactured very different items, so this method of promotion spread to other countries and continents.
For a while, coupons stopped offering free products, simply to have a price reduction, but this did not stop being a very effective tool. Typically, discount coupons were placed in mass media such as newspapers, magazines, or even on the product itself. During the 60s, it became an exclusive task on Sundays to clip coupons to consume them in the purchases to be made that same week.
