There's a chain pizzeria called "Little Cesar's" that charges about 5 dollars for the pizza, but I'm not sure if they deliver or not. I would assume not though, but they pre-make the pizza hot and fresh, so all you have to do is go in through the drive through, or walk in the store and buy it.
I tried Little Cesar's many years ago and it was incredibly nasty. I reluctantly (I mean REALLY reluctantly) tried the new five dollar pizza and it was actually not bad. It has undergone a dramatic improvement. I would go with this if you have one in your area.
