What would you think of this Pizza ordering program (or app)?

I have an idea for a program...perhaps an app. You say what kind of pizza you want, how big, what toppings, and it tells you which place can deliver it the cheapest in your area. It's really simple, but I figured it could be useful. It would also keep track of what deals are going on, and offer you them, or give you deals which correspond with what you want. What do you think? Dumb idea? I've never been all that creative.What would you think of this Pizza ordering program (or app)?
