Download version of black plague: $19.99 == 19.99EUR?

[cpoc]

Hello,

I wanted to purchase download version of Penumbra:BP, as announced on your page, for $19.99, but on GamersGate it shows 19.99EUR.

The paradox situation is that the box version will be cheaper than the download version here (Czech rep.). But i would prefer download version. Any advices how to purchase it for $19.99 with paypal?

Thanks.
