I didnt find any decent games from these deals atm. Waiting for new deals (1min left ). Loving Portal2 - im in chapter 8 now and its just awesome. Co-op is awesome too.
You could use moneybookers. Where i live - moneybookers have a partner whose local bank account is being used with the service. So i just transfered the money to that account and worked with those comfirmation codes and got my money to where i needed it. If Finland has one too - it should be simple. All You need is a bank account.
