Except that other pizzeria two minutes away isn’t only pricing it’s pizza for walk-ins either, it’s offering free delivery to steal the customers further away from the other pizzeria. They both would have the charge built into their pizza, so it’s irrelevant. Unless that pizzeria doesn’t do any delivery at all, in which case the first pizzeria doesn’t have to worry much as it has all the business for people who don’t want to come in and pick up pizza.
