Restaurant.com offers gift certificates at really reduced prices. Normally, a $25 gift certificate costs $10. Through Sunday, January 9th, you can get 70% off that price with the code "PLATE". That makes the price only $3. You can print the gift certificate immediately from your computer!
Over Christmas vacation, my sisters and I went out to a random Mexican restaurant. It was such a fun time as four adults now to get to hang out for a little while (we live in different places), and using Restaurant.com, for all four of us to get entrees, drinks, an appetizer to share, plus taxes & 18% gratuity, we spent $24 out of pocket. That made the evening even funner!
