I have put in $85 in pledges so far and donated some to our KGB cause. I can't afford to do anymore for a while.

What do you guys think is more important? Pledging to the game for the tax free etc or adding to the KGB cause? I assume there is no Tax free option once we buy the town etc? I am not sure how all that works. I definitely want to buy a house, I am fine if it is with in game money.
