Free samples are small portions of products offered to consumers at no cost. Companies use free samples to introduce new items, encourage trial, and attract potential customers. These samples can be found in stores, at events, or through online promotions. Consumers often appreciate free samples because they allow them to try products before making a purchase. This practice is common in various industries, including food, cosmetics, and household goods. By sampling a product, customers can make informed decisions about whether to buy the full-sized version of the item.
