the way its being stated, suggests the price won't change for 24 months, however, I only need a 1yr agreement? so the 2nd year I can quit the service if I wanted to (i.e. no more obligation) yet the price should continue to be the same?
Term agreements often include an Early Termination Fee if you cancel before the term is complete. Be sure to read the fine print carefully. Note that Comcast can increase various fees as much as it wants at any time, even if an Agreement is in effect.
