Cheapest The witcher 3 key for steam ?

CDP monopol = only GOG keys.

It got region locked so most of the regions with lower prices can no longer trade :\ you missed out champ

I think you can only get the Steam version from the Steam store. Every other seller should be the GoG version, unless I am mistaken.

sometimes steam is the cheapest, sometimes not.
here is some site you may find usefull.

They are promoting their own service (GOG). Afaik only way to get it on steam is through steam itself

It's a similar situation to GTA:V. If you want it on Steam - buy it on Steam.

Exactly, I got it on gog with all expansions for 20€. In that moment it was like 60€ only for game on steam ... difference was even bigger than with GTA V ehh.

Nuuvem has it for $30. And it's GOG!

I don't know prices for your country, but it may be cheaper on G2A.

The only place you'll get a Steam version of Witcher 3 is from the Steam Store.. so no keys anywhere for it.

You won't find a Steam version cheaper then on Steam unfortunately at the moment. All others on price comparison pages are GoG versions.

Managed to get mine for 6.5 keys before it was region locked.
Back then I was not aware that they could region lock later on, so I bought it thinking it was safe.
Thankfully it seems like it will still work for those who bought it before the lock came into being.

as far as i know there are no Steam cd-keys for witcher 3.
the cheapest steam version is from the Canadian store,with the 20% discount it's $48 here (canadian dollars,$48CAD equals around $40 USD )
