NHL: where to watch cup game after they been played

Hey I need advice my hockey subscription is basically running out when game 5 airs( stupid timing) and I’m quite broke this month. I’m from england.

I could use one of those live streaming services but I between Saturday and Monday I’m travelling, so it seems like I’m missing my first ever Stanley cup final since I’m a new hockey fan😭😭

It would SERIOUSLY mean the world if someone could help me find a website or app that gives you free full hockey games after it’s aired, I doubt anyone knows any, I don’t want to watch just highlights as I mentioned it’s my first ever Stanley Cup watch and I NEED to watch it but I won’t be available on the day the final airs i think. Even if the quality sucks, I just want to experience the final game… :(

Will it go to game 7 do you reckon? Canes or Knights??
