This deal has ended.
Through Father's Day (Sunday 6/17), take 50% off dining certificates from Restaurant.com with coupon code DAD plus get a free $15 credit at LobsterGram with any order (fyi: use code SPG710 for 10% off at LobsterGram). 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 $5 with the 50% off coupon code. Obviously, not all restaurants participate, but there are more than you think.
