Promotional sampling is a marketing technique used by companies to introduce and promote their products to potential customers. It involves offering free samples of a product to consumers, typically in a retail or event setting, in order to generate interest and encourage future purchases. This strategy allows companies to showcase the quality and benefits of their products, while also creating a positive brand experience for consumers. Promotional sampling is often used as a way to create buzz and generate word-of-mouth advertising, as well as to gather feedback and insights from consumers. It is a powerful tool in the world of marketing, as it allows companies to connect with their target audience and build brand loyalty through the power of a free sample.
