Minimum cash needed to purchase one time offer?


Does anyone know if there is a one time incubator offer if you progress above 4000 trophies and enter into the new arena 8 for the first time? If so what is minimum cash needed to purchase it? Since I know if you try and top off your cash after you receive the one time offer, that the offers disappears after you’ve purchased more cash through the game store.


Yes, there will be an one time offer when you enter arena 8.
I don’t remember the actual price, but might be no more than 2000 cash.
