I don't think there are typically Black Friday deals for streaming services, but it's worth a shot. After YTTV jacked up the prices I've just been looking for "alternate streaming methods" for games that I care about. The fact they dropped FSN again along with Hulu and others means there is no decently priced option out there at this point that I'm aware of. I don't think Fubo has it either anymore?
It's sad, I would gladly pay the $45-50 a month for what I had with YouTube TV, but I'm just done with it at this point. They did the whole "add more forced channels that no one asked for to justify another price increase". I'm a bit surprised we haven't seen any a la carte service pop up yet.
I'm also surprised Fox hasn't started their own service where I could pay about $10/month for all their stations, which would presumably include FSN. I do know there has been talk of ditching the regional sports network structure for a while, so maybe that plays into it. With a new NHL broadcasting contract coming up in the next year anyway, maybe FSN won't even have many games after next year anyway though.
