Restaurant.com slashes 70% off any gift certificate via coupon code "SEVENTY". That's not as good as the 80% off coupon from last month, since expired, but it's still the second-largest discount we've ever seen from Restaurant.com. This coupon cuts $25 dining certificates to $3 and $10 gift certificates to 90 cents. Restaurant.com's gift certificates are redeemable at local restaurants across the United States. Some gift certificates have restrictions, like dinner-only or a $15 minimum. (Each restaurant lists its individual restrictions.) Deal ends July 13. Close
