Witcher 3 29.99 on GMG?

GOG key btw ^^

showing as $36 to me

It is $33 in my country for Steam ^^

I see $36

It's not an error. It is the vip deal; they have special deals which are only available if you have an account. You can't use vouchers but can use GMG credit, if you have any.

it's a VIP deal I would have bought that but I want to buy DLC with it too and I can't buy the DLC for witcher 3 if I didn't purchase it from Steam or for steam that key only works for GOG
