Restaurant.com Gift Certicates are a great way to reduce your spending if you want to eat out. They are like a coupon to a specific restaurant as most of them will be $25 off your purchase of $40 or more or something to that affect. Be sure to read all the details and get the best deal you can. If you spend only $1.50 out of pocket, then another $15+tax and tip at the restaurant you are saving about 50%. If you aren't interested in any cash back feel free to go directly to the website Restaurant.com.
I am posting this on a Friday just in case you need some more options of places to eat on the weekend and want to reduce your expenses. But personally if you don't need it I would wait until another 80% discount comes around as they do very frequently.
