Discontinued products are items that a company has stopped producing or selling. This can happen for various reasons, such as low sales, changes in consumer preferences, or the introduction of newer models. When a product is discontinued, it may no longer be available in stores or online, and support for it may also be limited. Consumers often seek discontinued products for nostalgia or to complete a collection. Some may turn to secondary markets, like online auction sites, to find these items. Popular examples of discontinued products include certain models of Apple devices or specific flavors of Pepsi.
