Product warranties can be a successful sales tool for retailers and industries. For instance, AppleCare offers a comprehensive and flexible product warranty service that covers devices, accessories, software, and technical support. Customers can purchase the service as a one-time fee or a monthly subscription, and it can be transferred or canceled at any time. This helps Apple increase its sales by enhancing its brand image, customer loyalty, and cross-selling opportunities. Zappos is another example, as they offer a 365-day return policy with free shipping and no restocking fees, as well as a lifetime warranty that covers any defects or damages that occur during normal use. The warranties reduce customer risk and increase customer satisfaction, thus encouraging repeat purchases. Lastly, Costco provides a generous and flexible product warranty policy that covers most of its products for unlimited time or extended periods. Plus, customers can return any product or cancel any membership for a full refund. This creates customer value, trust, and loyalty which in turn increases sales for Costco.
