Through 12/25, take 70% off dining certificates from Restaurant.com with coupon code GIFTS, the largest coupon I've seen from them. The dining certificates are printable credits that you take to local restaurants. The restaurants give the credits to Restaurant.com, who then sells them for less. For example, a $25 certificate normally sells for $10 but is now only $3 with the 70% off coupon code. Obviously, not all restaurants participate, but there are more than you think. Also, be careful to read the fine print as many restaurant exclude Saturday, alcohol or other things. These make great last-minute gifts as you can email, print or stuff these in a stocking through Christmas day!
