2000 donuts for $500,000?
I'd spend all that cash on bonus leveling and get some donuts that way. (Australia raised some kind of rate on video/mobile games, so yes the price went up.)

During the Level 41 update, I spent tens of millions on bloodmobiles for the XP level ups. I posted my results here and someone worked out the math to be about $1 million per donut. So in-game cash, in a way, can be converted. Bloodmobiles give a good return on XP's; just buy a bunch (like a house farm concept) and keep leveling up.
