Going to buy, have a query regarding currency

[zeb]

Hi,

I live in UK and am going to buy the game. The e-store displays price in many currencies, and the game costs 10.42 GB pounds. Is the transaction actually done in pounds ? I ask this because my bank would surcharge me if the transaction were done in dollars.
Any UK customer to answer me ? (and no a high-street store is not an option as I am going to purchase the Linux version).
