How I wish I could take advantage of this, but there's not a single restaurant in my area that I like on Restaurant.com. I am not one to pimp useless items or promotions. However, I highly recommend you at least check the site out NOW because through 8/31 they are giving 80% off on their certificates with this coupon code:
That means you can get a $50 certificate usually priced at $20 for only $4. This is not a scam. If you must dine out rather than cook your own food, this is highly cost-effective way to do so. I have friends who use them all the time. Some have even convinced the restaurants to let them do take-out using the certificates. It's all about building a relationship with them first though.
