The Restaurant.com $25 for $3 is back again. Plus get a $15 FREE gift from RedEnvelope. Use code: SNOW through 12/17/09. Great for teacher gifts!
Personal comment: We used our first Restaurant.com $25 gift certificate this weekend and it was great. We had a nice meal and paid only $23 including tip. The restaurant was super nice about us using the gift certificate. You just need to make sure you read the requirements for the restaurant you will be using it for. Our restaurant required us to have an order of at least $35 (before coupon was deducted) and it had to be for at least 2 dinner entrees. Usually it does not cover alcoholic beverages.
