Dude your prices are exactly the same as official Steam store. Not to mention Superhot for example which you can get from G2A for about 4euros
Well, I did use the (on-sale) steam prices as guidelines.
I'm not trying to compete with keys from questionable sources on G2A - in fact I believe G2A/Kinguin should be avoided by anyone who loves PC/Indie games because of their scummy business practices but that's just my two cents.
Well I'm just trying to point out that Steam Accepts Bitcoin too now so what is the point in buying games from untrusted third party for same price ? And I know about G2A's business but still, I never heard they scammed anyone for their key
