When a product is sold, that returns sometimes because that is damaged or by any other problem. It might be sometimes because of customer return. Several brands offers certain day return policy so customer will return the product being unsatisfied by the performance of the product, not physical condition. And Sometimes the item can be damaged while shipping. And sometimes its supposed to be refurbished product in the case of overstock. And they are then repaired if damage and sold fore less price. Thats how you can save money from it. Do not always bargain in the stores, check for refurbished products, you might save a lot more from it. You can either buy directly buy from the stores otherwise from retailers.
