Hello community, I'm new on this forum and on this platform. I have The Witcher 3 because it was a gift from nvidia, now I want buy the expansion pass for get the games(the witcher 1 and 2), but I have a trouble with my credit card, it not have sufficient funds, I can not make a transfer because the funds will be available the monday after the offer of expansion pass expired. So I want know if I buy the Online Game Code on amazon this game code can be used on gog.com

When I bought my gtx 970 amazon gave me a game code for nvidia webpage and then nvidia gave me the game code for gog.com
