I'd like to know if paying for a game with Paypal would be possible for someone from Poland (like me, obviously ;)). I don't ant to transfer money to my Paypal account for nothing...

I can pay small amounts of money (up to $15 or so) without transfering it to my paypal account myself.
And i'm pretty sure that they will not forget about their own country, and i see no reason why Paypal wouldn't do it, either.
So if you got a PayPal account, and you know how to get the money there, everything should be fine.
Obviously i can not prove it, though.

Credit cards work without any problems, so I don't think you have anything to worry about.
Besides, isn't it possibe to withdraw money from Paypal?

I guess you're right, tenbux shouldn't be a problem... but I've read about some problems with PayPal with sending money from Poland to USA and other countries, so I had to ask you :)
Onwards to buy Disciples II Gold :)

No, no, the problem was that you couldn't transfer your money from PayPal to your Polish bank account (they used to accept banks from US, Canada and some EU countries only), but it was solved about a half year ago and now they are also accepting Polish banks.
