Today Apple added 8 new currencies to AppStore. They also tweaked the Euro prices of in-app purchases and apps. For example, our 500 gems package went from 3,99 to 4,49. Since these are standard price points across all of the App Store, we are unable to revert the change. We can only set the price tiers, and Apple sets the actual prices for each region as they see fit.
