Product sampling refers to the practice of distributing free samples of a product to potential customers in order to promote and increase awareness of the product. This marketing strategy allows consumers to try a small portion of the product before making a purchase, giving them the opportunity to experience its quality and benefits firsthand. Product sampling can be done through various methods such as in-store demonstrations, mail-in samples, or through online campaigns. It is a powerful tool for companies to introduce new products, gather feedback, and ultimately drive sales by creating a positive and memorable experience for consumers.
