This deal has ended.
Update: This has been extended! Get 50% off dining certificates at Restaurant.com via code DEALS through today only. This drops the price of a $25 gift certificate, which sells for $10 to $5. Not all restaurants participate, but there is a wide selection to choose from and you can search by area. Just make sure that you read the fine print as many restaurants exclude alcoholic beverages, weekends, and holidays and set their own spend minimums.
