Advertisements I called Comcast here in Atlanta and they told me the card was free IF you turn in your cable box. Otherwise, it's $5 each, just like a box would be. My TV has a tuner but without a card, it's practically useless as they frequently change the channel lineup. I want to keep my cable box, so no cards for me. I guess if I had a S3 I wouldn't need the box, and then I could get a card. But of course, I'd want two, so I'd still end up paying $5 more.
