Macy's offers the Hybrid Men's Star Wars Holiday Sweater for $19.99. (Amazon charges the same.) Pad your order with a beauty item (they start at $2.55 via coupon code "FRIEND") to bag free shipping; otherwise, shipping adds $10.95. That's $40 off and the lowest price we could find. It's available in sizes S to XL.

Update: Amazon has dropped its price to $17.99 with free Prime shipping.
