Macy's offers the Martha Stewart Collection Collector's Enameled Cast Iron 6-Quart Round Casserole in Blueberry for $49.23. Pad your order with a beauty item (they start at $3) to bag free shipping; otherwise, shipping adds $10.95. That's tied with our mention from two weeks ago, $131 off list, and the lowest price we could find. It features an enameled interior and is oven-safe to 500 degrees.
