From the very beginning, giving products for free is a method that is considered very effective to get customers. It is because something free will be very difficult to stay away from. One more reason why this strategy is considered necessary is because often a customer has not bought a product, because they have never tried the product. Therefore, to give free products, a company can just choose an event for the purpose or directly offer free samples door to door to prospective customers. If the product is in the form of services or digital media, the company can offer a free trial or allow customers to try it free to attract the interest of potential customers towards a product.
