That is likely trying to compare an unknown Chevrolet to an unknown Ford model. You would have to post a specific channel line-up or package so that we could compare apples to apples and oranges to oranges, so to speak. What cable company are you referring to?
As Jim said you need to compare apples to apples. What channels do you currently get? Is this a promotion because you're under contract? Will your internet bill go up if you unbundle? What is the total cost of service over the life of the contract?
That's why I like free digital TV. 24 channels, all the major networks in better HD than cable or satellite, movies, music videos, classic tv, lifestyle, and no monthly fees after the initial investment.
