Macy's offers the American Rag Men's Mini Houndstooth Shirt in Grey for $17.99. Coupon code "FRIEND" cuts it to $12.59. Pad your order with a beauty item (they start at $4) to bag free shipping; otherwise, shipping adds $10.95. That's tied with our July mention, $17 off, and the lowest price we could find. It's available in sizes S to XXL. Deal ends December 11.
