Good question, i never bought the max token deal, erm, mostly i take the one thats around 15 euro, but couple times i used the one 38 euros. I think in total i have spend, 120 euro or something, maybe a bit more. But then again, i got almost all buildings maxed out aswell.
But, stadium is extremely expensive, my next upgrade for that is around 25 million. So for now im not gonna buy more tokens, i might do it, next week, to get some stars on players.
