WildHobgoblin: As for Gog, paying with dollars now is just cheaper than paying in euro, so I'll just go with that for the time being.
ZFR: Just curious, doesn't your bank charge you anything for the currency exchange? I pay around 1.75% for the exchange when I buy in USD. So even if the GOG euro price is a few cents higher than the mean exchange price, as it is at the moment, it's still better to pay in euro.
No, I don't pay anything here, and I'm pretty sure it's the same for all the other banks in this country. So paying in dollars is usually preferrable, especially since we can get dollars at a better price than euros - or rather used to, with the crown's articificial devaluation by the national bank it soon may be better to pay in Euros because the dollar went up by a whopping 25%! You used to be able to get it for 18-20 Czk, now one dollar costs about 24-26 Czk. While the Euro went up from 25 to 31 and then dropped again, so now it's about 26. So yeah, before the dick move which lowered our currency's strength (which was to supposedly 'help' the economy but because export companies often use imported parts or goods to create their products, it doesn't help them and has actually driven their costs up as well as all the import companies and everyday prices have gone up - only the banks profit from it), it was always better to buy the games here with dollars for us.
