Through 10/31, take 80% off dining certificates at Restaurant.com via code TREAT. For example, a $25 gift certificate, which sells for $10 - $15 (depending on store), is now only $2 - $3 and a $10 certificate, which sells for $4 is just $0.80. This code will also get you a free $20 off $50 online coupon code to Mrs. Fields cookies. 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.
