Free samples are small portions of products offered to consumers at no cost. They are commonly used by companies to promote new items, allowing potential customers to try before they buy. This marketing strategy can be found in various industries, including food, cosmetics, and household goods. Businesses often distribute free samples in stores, at events, or through online promotions. By providing these samples, companies aim to increase brand awareness and encourage purchases. Consumers benefit by experiencing products firsthand, helping them make informed decisions about their purchases.
