Through 12/6, take 70% off dining certificates at Restaurant.com via code GIFT. For example, a $25 gift certificate, which sells for $10 - $15 (depending on store), is now only $3 - $4.50 and a $10 certificate, which sells for $4 is just $1.20. Although this is not the deepest discount we have seen from them, Restaurant.com restocks its certificates at the beginning of the month so this is a great time to buy. Not all restaurants participate, but there is a good selection (15,000+) to choose from. Just be sure to read the fine print, as many places exclude alcoholic beverages, weekends and other things.
