This is an American website but this is the cheapest price that a popular Indie game will ever get at third party sellers. Please note that this is the European edition of the game but I think it just affects the ratings. Just be aware that this website may be dodgy for your liking but if you're desperate for a good steam game, then dive in!
Lowest price for this was on 7 August 2018 on Steam at $1.60 AUD.
Has also been in a bundle in the $1 tier.
Sorry but given this and its age it is not such a great deal, especially since this website is not an accredited reseller and you could end up with dodgy keys.
Plus, you need to change the title. Wrong store in the title.
Last I checked Instant Gaming was a grey market retailer.
If you're going to buy grey market then why not buy from the cheapest one?
Cheaper at G2A. Cheaper at Kinguin. Probably cheaper at others…

Title appears to be Badland, not Badlands
