I've never trusted buying off of them cause I don't want my bank info stolen but I've recently realised I can just pay with paypal lol. Can anyone recommend which of those sites that sell keys for steam games are legit? I just need 3 copies of l4d2 to game with my friends.
I've used G2A several times and never had an issue. You just have to pay attention to what the restrictions are. Sometimes it will say you'll have an account that you get the details for although I've never done that, or certain keys are region locked so you may need a global key depending on where you are.
