Need a set of dishes? Looking for just the right lamp to put in that corner of the den? On the prowl for the Ferrante and Teicher LP that will complete your collection of Sixties lounge music? This is the place for you. Red White & Blue is a veritable department store of used wares, containing not simply aisle upon aisle of clothing, handbags, and shoes but entire sections devoted to furniture, household goods, electronics, books, and records. If you don't find what you're looking for the first time, don't despair; new old merchandise is arriving constantly. And sales benefit a good cause: the Vietnam Veterans of America.
