Alternatively, you can also get them at Rakuten for an additional 20% off with promo code TOYS20, which brings them to about 50% off list - one promo per account, must be logged into your account to use promo, total discount is limited to $20 (so $100 before promo code). * The Goblin Village was showing me a $5.99 shipping fee on Rakuten - not sure if that's a regional thing or if it will apply to everyone.
