The best deal for networks is over-the-air TV. I had to go to some lengths to get this to work, as we're halfway between LA and San Diego, 60 miles from either. Use with Tivo or another DVR from ChannelMaster or Silicon Dust or Amazon Fire TV Recast.
Next best deal for now for networks is locast.org but they're not in NC.
Sling is having a free "Stay in with Sling" promotion now where you get the Sling Blue channels from 5pm to midnight. They don't say how long this will go on. Sling has NBC and/or FOX in some markets, but not all and not NC. Ordinarily it's $30 per month; a special gets you $10 off the first month.
We used Youtube TV for a while. It was OK and $50 per month; it had the local broadcast stations. We only watch about two cable channels, which I why I pursued the OTA antenna. But $50 is better than $90. They have limitless recording and on-demand programs. You can get a 14-day free trial. Hulu Live is slightly more and similar; DS has that.
One of the biggest gripes is that every TV app (HBO, Sling, Youtube, etc) has its own, slightly different, user interface. This drives non-technical DW into rages. For my part, I can never remember what platform Program X is on, and end up searching the three or four we regularly use. And the Sling app for Samsung Smart TV is awful, while the one for Amazon Fire TV is wonderful. Why? It's partly because Samsung asked themselves "How few buttons can we manage to put on a remote?" So there is no button that will bring up Sling's home screen. I've ordered the Tivo Stream 4K, which looks like a big, hardware-based Sling App, but they swear it runs 4000 other apps and that I can return it if I don't like it. I'm hoping it will bring consistency to the various apps. $50 now, introductory special. I've had Tivo boxes for years and love them.
