Food&drinks-wise I think I am prepared quite well. My fridge is full of 6 packs and I stored enough many popcorns and other junk food. I am filling up the fridge whenever it starts to get empty so it means I am almost always ready in that department.
It is more important to get prepared mentally though. I am watching the news all the time to learn which team is doing what. New coach or maybe new players? I need to know about these developments because they affect the way I make bets. I don’t know if I need any other preparations I think that’s all I do before the next season starts.
