Korvette used "membership cards" (which it distributed in front of its stores and to surrounding offices) to style itself as a retail cooperative. In doing so, Korvette's was able to accept deep discounts from suppliers, something that competing department stores, such as Macy's and Gimbels, could not do. In fact, Macy's and others filed numerous "fair trade" lawsuits against Korvette's to stop it from undercutting their prices. None succeeded. The lawsuits helped Korvette's by calling attention to prices so low that competitors thought them illegal.
