The only legitimate comparison is NCHC.tv, which is $117. They do offer a single school only pass which saves you a whopping $9 ($108). You do realize that subscribing to Flo also gets you all the GLIAC sports for NMU as well, right? I mean, I get not caring about other college hockey games, but I routinely switch to other games at intermission, or have watched several college baseball games on Flo. I watched the ASU/Alaska Donnybrook live solely because I subscribe to Flo. If it's too expensive for you, don't subscribe. For what is offered, it's incredibly reasonable.
Edit - I will add, I'm not forgiving all of Flo's warts. There's definitely things I wish they'd improve, most notably, I have NMU saved as a favorite, yet I always have to search for their games. That said, probably 90% of the problems aren't Flo's fault. They are with the original broadcast. And there's nothing any streaming service can do when given a substandard product, like what Ferris has been putting out most of the last two years up til a few weeks ago.
