Have you tried Restaurant.com? If not, you are missing out! You can purchase gift certificates for really cheap! Think of it as buying a coupon. Some deals are $10/$20 purchase and up.
Right now for Cyber Monday you can get a $25.00 Gift Certificate to a local restaurant for only $2!
I also have to say, Restaurant.com has great customer service if you ever run into any issues.
Just click the image above to browse through current certificates!
