Today, you can still grab the 90% off Restaurant.com certificate deal. Just use the code WOW at checkout. I purchase two of these yesterday, our family uses this website alot and we have saved a ton of money eating out this way. My only complaint is too few selections in our area. This is a great Christmas gift for teachers, postal workers or anyone on your list, who might be difficult to shop for.
Make sure you pay attention to the fine print on your certificate. All the certificates require that you spend a fixed amount or more to use your coupon and usually require an 18% gratuity, depending on the restaurant you choose, there may be additional restrictions.
Right now you can grab $25 off certificates for as low as $0.50!
