Get 80% off at Restaurant.com with coupon code CLEARANCE.  Valid through 12/31.  Make sure there is no extra space before and after the code in order for it to work.  Here is a screenshot for your reference.  They sell many $25 gift certificates for $10 each.  After 80% off, a $25 gift certificate can now be purchased for $2.00.  There are also $10 certificates for some restaurants at just $4, making them $0.80 each after the same coupon code.  Be sure to read the rules and fine print of the certificates as each restaurant is different.
