Through 7/31, don't forget that Restaurant.com is taking 80% off dining certificates via code SAVE. For example, a $25 gift certificate, which sells for as low as $10, is now only $2. Not all restaurants participate, but there is a good selection (18,000+) to choose from. Each restaurant has their own fine print and restrictions which may exclude alcoholic beverages, weekends, and holidays. Also, most certificates have a minimum spending threshold that must be met to use the certificate.
