Can’t speak for the US as a whole but everywhere I’ve lived Domino’s is the cheapest. I can get a medium 2 topping pizza at dominoes for $6.99. We have 3 family run traditional pizza places within driving distance of where I live, for a 2 topping medium pizza they cost: $14.75, $15.99, or $18.99.
I will copy my response to another poster:
