Remember, the government and CRTC never said it was about savings, but rather about choice. My guess it will be like soft drinks: if you buy a case of 12 you get a bundle price, but if you want to choose specific flavours individually, the price rises.
I'm on sat also and I don't expect any tv provider to come up with a system that will allow you to get the few extra channels that interest you without including a bunch of useless ones. That being said having the basic and adding 1-2- 3 channels will probably cost more than buying the grouped packages. But you never know it might happen????????? maybe.
