Don't you mean 60 Euros?
People buying games in UK have better luck than those dealing with Euros because some European countries sell them at the same price as if it were in US, i.e, $59.99 = 59.99€ regardless of the actual price conversion. And even worse they sometimes have it being sold for 70€.. only 30€ away from hitting 100€. lol
I've just checked to make sure and Netherlands uses the Euro and the Dollar... Why the hell does Netherlands use two currencies?
Anyway, I wish Portugal and Spain wouldn't have changed to use the Euro but it's done and what they've gotta use.
