Consider this your lesson in the basics of trading and the difference between a ROW tradable steam gift (which has 0% chance of any revoking or scam) versus shady unauthorised grey market resellers with EU-region only locked steam keys (which have a significant chance of being revoked and cost less because they come from Russian/CIS retail)

At the end of the day you can get lucky with your key not being revoked, but if it does get revoked you end up paying much higher than you would have for a normal ROW tradable steam gift because you need to buy it again and again after being revoked.

More so, grey market seller keys have a significant %age originating from chargeback frauders in which case not only are you NOT supporting the developer who actually made the game which you are enjoying in the first place, but in fact it COSTS them money from credit card chargebacks. Which is why small indie developers have come out & said please just pirate our games instead of buying them on the grey market, a lost sale is one thing but we can't afford to pay for chargebacks.

Other than that, EU- region locked games always trade for less than ROW games because they are accessible to less people, with ROW gift there is no worries of Steam region locking.

Lastly, posting repeatedly in someone else's thread with low-ball offers and referral links is considered highly rude and ill-mannered but I guess you still have a lot of growing up to do both in life and in trading.

Try to have a nice day, there is no point getting this upset over something you cannot afford 😹👍
