Through 8/23, take 70% off dining certificates at Restaurant.com via code STEAK. For example, a $25 gift certificate, which sells for $10, is now only $3 and a $10 certificate, which sells for $4 is just $1.20. While this is not the highest discount we have seen, Restaurant.com has just restocked its certificates so now is a great time to buy. Not all restaurants participate, but there is a good selection (11,000+) to choose from. Just be sure to read the fine print, as many places exclude alcoholic beverages, weekends and other things.
