Koodo should offer an incentive so when you add more phones to your account you get a slightly discounted amount off each plan. Example (each plan being $50 initially) - One line is $50 Two lines is $95 Three lines is $135 And so on... This would make people want to sign up more people to their account and everyone would still have separate plans. Not saying current things like unlimited calling between lines isn't nice, but give people more reason to spend less for more. Just a thought!
