Just so that I understand correctly, are you saying that if they give you extra services for free, they will knock 30-40 off your bill? Or are you saying that if you have, lets say a $100 internet bill, and they add phones for which is normally a $40 service to your account, that they will make your total bill $30-40 cheaper($60 total bill) or that with the bundled service, internet comes down to $60 and you pay $40 for the phone?
I doubt anyone is giving away *free* service and if you're paying more for a bundle, then you arent being forced into anything since you have a choice. They are discounting services on the line item but its still more because you are bundling. That doesnt mean that the internet service, which costs $100 normally is actually really only $60 and they are MAKING you get phone service as well for $40.
What Im trying to say is, nothing is bundled for free and they will never add additional services for free because you bundled. Youll always pay more for 2 services rather than one, even if they make it seem like a deal with each costing less separate but in a bundled pair. Im going to use $80 as the bundled internet option since thats more appropriate.
$100(internet) + $0(no bundle) = $100
$80(internet) + $40(phone) = $120
Youre not paying less because its bundled, youre paying more because youre adding service on. Also, IF on the chance your bill goes down because of the bundle, who cares that you have TV, dont use it!
