Hi - Open Box TVs are sometimes returned TVs; perhaps because of buyer remorse, too big for the space, too small for space, they changed their mind, or just wanted to upgrade. So, yes, in a sense they are all used. It can also be a televison that was used for display purposes. Geek Squad checks them out beore they are offered up for sale. Many consumers find them to be a great value, while others prefer to have a brand new TV. Please check with your local Best Buy regarding their policies for open box. ^Cris
