1st channel: $30 (note: this can be any channel)
2nd channel: $15
3rd channel: $7.50
4th channel: $3.75
etc.
etc.
So you may think hey if I can get 85 channels for $60, I should be able to get 5 channels for $15.
But my math (it's irrefutable) says it will be about $55. The next 80 channels are only going to be $10.
