ThinkGeek takes 20% off orders of $50 or more via coupon code "GIFTQUIK". (That same code instead cuts 25% off orders of $100 or more, or 30% off orders of $150 or more.) Shipping adds $6.75, or bag free shipping on orders of $75 or more. Deal ends December 25. A couple best bets, with prices after coupon: Need it by Christmas? Order by noon ET on December 22 and choose "Express" shipping for $24.95.
