Now take 60% off dining certificates from Restaurant.com through 4/30 with coupon code APRIL, plus get a free $10 certificate with any order. 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 $4 with the 60% off coupon code. Now, the additional $10 promo nets you $35 of dining certificates for $4, matching their best deal ever. Obviously, not all restaurants participate, but there are more than you think.
