I have a Visa Vanilla Gift Card and I know it won't work for regular purchasing since GOG.com is based in Poland, but it should work if I attach the same card to my PayPal account and buy my games like that right? Even like that I get this error " Check your account at your card issuer before retrying this card." and I can't finish my purchase. I tried using PayPal as a guest too and nothing happens. How can I transfer my money to buy these games? I really just want to cash in on this Summer Sale.

An www.weststeincard.com/ online card for payments is better for you, then you can make any purchases. Now it is not a problem to open such a card, it is done in a couple of minutes. I myself use this type of payment, it is very convenient.
