Sling TV has an a la carte approach to channels that separates it from its competitors. Sling TV offers two basic packages: Blue, with 43 channels for $35, and Orange, with 32 channels for $35. You can get them both as a package deal for $50, and you can add small packages of other channels, called Sling Extras, for small additional fees.For NFL fans this is a mixed blessing. I like it because it lets me get the channels I want, but it’s also a tad confusing. Some channels are available on both Sling Orange and Sling Blue. Orange is basically an ESPN/Disney package, while Blue offers a Fox/NBC package. Blue also includes The NFL Network. Your best deal, if you want a broad selection of channels, is to subscribe to the combo for $50.Sling TV’s Extra packages, besides such common offerings as Showtime channels, cost from $6 monthly. For pro ball fans, the $11 Sports Extra comes with 15 channels, including NFL RedZone. What you won’t get, though, is your local CBS affiliate. For that, Sling TV urges you to use an over-the-air antenna. Sling TV offers its own streaming device, the $99.99 AirTV 2 More
