Elle85: EDIT
I've just bought it but on my card it charged 6,23 euro. Not a big problem but is it the same for all of you (euro zone) ?
Catshade: Impulse will always charge you with US dollars. That 4,71 € price shown in the store page is Impulse's own conversion; Your bank usually have a different (and more expensive) conversion rates (plus maybe currency conversion fee). A little bit disingenuous on Stardock's part, really...
I have a debit card and not pay conversion rates so they should charge me 4,71 or something like it, for sure they don't have to charge the same amount of dollar in euro (the classic 1$=1€ ), but I don't really care about it but since they charge instantly I would have my game :p
