I've posted this freebie before, but it's still available this month, and its a great offer so much sure that you take advantage of it!
Restaurants.com is giving away free 10.00 gift cards to everyone that you invite on facebook, or through email. If you would like to give yourself a free 10.00, just send it to your secondary email address.
Also, if you have multiple email accounts such as I do, you can use all of the codes from all of your email accounts and redeem them all on one restaurants.com account. Just make sure to redeem the codes one at a time.
