Roman5: Welcome to the forums and community
As people have already said: you will be charged the same ammount as all other users worldwide, you will just be charged in Pound sterling instead of US Dollars
Wait... I'm getting contradictory information from your post.
"As people have already said" would be "a game for $US 9.99 will cost you £UK 6.22, or whatever the current rate is".
"you will be charged the same ammount as all other users worldwide, you will just be charged in Pound sterling instead of US Dollars" can easily be interpreted as "a game for $US 9.99 will cost you £UK 9.99".
The first statement is true... if the post was meant as a joke, sorry to ruin it.
