Update: Coupon also works on non-LEGO Star Wars items.
LEGO Shop at Home Facebook page has revealed that for 2 days only from December 5-6, that when you spend $75 or more on LEGO Star Wars Purchases, you will receive a FREE Shadow ARF Trooper. Spend $99 or more and your order qualifies for FREE Shipping too. If you are from USA, use code BARK. If you are from Canada, use code WOOF. Thanks to staff ncbarrett for the heads up.
