Is there a way to prove that a key is legit and works before buying it? Otherwise, people will trust established sites like g2a to get cheaper keys. Personally I have never bought keys outside of Steam itself because im too paranoid to trust anyone. Keys that don't work, or are obtained illegally, are a common case amongst resellers (im not saying you aren't legit, just saying).
I know this and I think there is one important thing here...trust.
You have the "Moderator" option at OpenBazaar which is used as an escrow service. For the future I think I just need to build some trust for my OpenBazzar Account but this takes time for sure.
Also illegal keys would be sold a lot cheaper than mine LEGIT ones

It would be kind if you could follow me at OpenBazaar also if you are not interested in buying something at the moment Smiley
