Arma 3 CD Key Russian

Hey guys I'm looking to buy a Russian Cd Key for Arma 3. I don't have a lot of money and I can't afford for it to become region locked. What should I

a russian key will obviously be reigon locked from the get go but dw its easy to play it normally just activate on a russian vpn then add as a non steam game

Look for a Arma III Pl key it's 15€ - 17€
