So as the title says, this website is selling original copies of MC Java Edition for $10 less upon conversion. Reviews state these are legit. How come they can have a legitimate copy of MC at $15. I thought 3rd party resellers aren't allowed.
I wouldn't trust it at all. Reviews can be written by the people who are doing the scamming to try and make it look real, so don't trust that, either. 3rd party sellers are illegal, so as webrosc said, report it to Mojang, and whatever you do, don't give the third party your information.
