Freemium is a business model commonly employed in the retail sector, where a product or service is offered for free with limited features, enticing users to upgrade to a premium, paid version for additional functionalities. This strategy allows retailers to attract a broad user base, showcase the value of their offering, and then monetize by offering enhanced features or a more comprehensive experience through paid subscriptions. Freemium models are popular in various digital services, apps, and online platforms within the retail landscape.
