Hello White5445, Ep8 is coming free soon , but I guess you are just interested in getting it one episode sooner.
I mean, why not get it right?
Because you will be able to buy episode 9 soon, so personally i would wait for 8 to be free, then i could buy episode 9, but you do you.
If you already bought it at any point just re download to get the updated version free
Ahh
