Except it seems you can use a passport (the red one?) AND fork out cash for the add-on.
For the standard rebuys during the first session (hour?) it's cash OR passport (green?) but I reckon if I dont have to stamp the green to be able to use the red then I'll just be handing over cash (bound to be cheaper).
I can see the general NPL public getting quite confused and the overall message would end up something like "if the white's in front of the pink, pot the brown".
