We've had several players comment on a discrepancy in pricing on an item in our store page, versus what you've been charged for a final purchase price.
Starting in early January 2015, Apple has made changes to the Value Added Tax (VAT) charged for in-app purchases. As a result of this change, you may see that your final purchase price is a slightly different value than the price reflected in Dungeon Keeper's in-game store.
While we do not have any direct influence over this change, we do apologize for any confusion this may have caused you. If you have any further questions about the changes to VAT, we advise you to contact Apple support for further assistance. We unfortunately exert no control over that part of the system.
