(WashuOtaku) A judge is warning JCPenney that if it ends up with empty shelves bereft of Martha Stewart-branded products, it’ll only have itself to blame. The company is in the midst of a tiff with Macy’s over which retailer is allowed to sell her homewares. Macy’s is claiming exclusive rights, but JCPenney recently went ahead and ordered products from her company anyway. New York State Supreme Court Judge Jeffrey Oing warned JCPenney’s attorneys today that the company took a big risk ordering up a bunch of towels, cookware and other items.
