If you use a 50% or 60% off coupon (posted above when available), you can get a $25 certificate for as little as $4, or a half off your food bill certificate for as little as $1.20! Enter coupons in the shopping cart or at the beginning of checkout. Before purchase, note the limitations for the certificate's use for that particular restaurant. Certificates are usually good for a year, however, I would use them within a month. You may also want to call the particular restaurant you are buying a certificate for to make sure they will accept the certificate. I haven't had any problems using these certificates, but some people have.
Coupons: The best frequent Restaurant.com coupon (70% off) is usually only available during the last week of the month. No coupon is usually available during the first week of the month, with coupons for 50% or 60% off being offered the rest of the month. Occasionally a coupon for 80% off is offered.
