@Lana - I personally don't believe any consumer communications company is "giving out" anything at $99/mo these days. The incremental cost per each additional customer is so small.

I recently switched to Comcast and was informed over the phone about the 2nd year guarantee. Early termination fees apply for the first 12 months only and that completes the contract. At that point the customer is free to do whatever - with the 'guaranteed' 2nd year rate being one option.
