Restaurant.com is now taking 80% off dining certificates via code SWEETIE through Valentine's Day. This drops the price of a $25 gift certificate, normally $10, to $2, or a $25 gift card that is regularly $15, to $3. They have a large selection of participating restaurants nationwide (more than 18,000), and you can search by zip code or neighborhood. Be sure to read the fine print for each restaurant, because they all set their own spend thresholds and exclusions such as alcoholic beverages, weekends, or holidays.
