I already own this game on steam and gog.
For collecting 7 stamps now I got a W2 code. Can I redeem it as a gift somehow so it's in my account's gift list?
Until it expires of course. Thanks!

Same for me. Anyone interested in a Witcher 2 Code? I guess, many people have already bought this game and have a spare code now.

Same deal for me.

Can't click continue to send it as a git, it seems. Will it work by just sending the code to someone?

Sadly, there's no way to add the gift code to your gifts tab if you already own the game.

The only way to turn it into a regular gift code is to hand it over to someone that doesn't own the game who you trust not to redeem it to their account. Note though that in this case, the gift code would be added to their gifts tab and not yours.

You can't help thinking that the gog people tend NOT to completely think through their nice special offers. :-)
