This was a deal too good not to share!
Right now restaurant.com is offering $25 gift certificates for $1! The only thing you need to do differently is enter the code JOY when you check out. The code is only good through 12/24/11 so don't wait too long!
Be sure to pay attention to the terms of each certificate before you purchase it. Some certificates state that they're only available for dine-in only. Others will state that a minimum purchase is necessary in order to redeem the certificate. So, just make sure you know what you're buying so there are no surprises when you redeem your certificate.
You should receive your certificate by email within a day or so. You can also log into restaurant.com and print it from there when you're ready. Just take the certificate to the restaurant with you when you're ready to redeem.
Also, as a courtesy to your server, tell him that you're using the certificate before he goes to grab your bill. And, ALWAYS tip on the full amount of your bill--not the discounted amount.
