Yes..Most items say like electronics, come with warrantees. So when a customer returns one because something is wrong with it, the company usually just gives them a new one and sends the old one back to the factory where they fix whatever was wrong with it and then usually sell them to a liquidator who inturn resells the item..
Normally they are listed as refurbished,since they are really not new, although they have been repaired to 'new' condition...
