Most Expensive In-App Purchases in Games?

[SHiNKiROU]

What is the most expensive in-app purchase you've ever seen in Android and iOS games? Which looks like the worst offender?

I found this: http://www.cnet.com.au/super-monster-br ... 344090.htm
$109.99, they actually earned money because kids don't know how much is $109.99. App is removed and new iOS has better parental controls to prevent that.
Candy Crush Saga, Real Racing 3: $30, $40, $100 powerups, buy a console game instead.
