Funny coincidence that all the games you're "selling" are included with the humble bundle (
https://www.humblebundle.com/). Since 100% of the purchase price goes to charity, you're pretty scummy. They even accept bitcoin as payment.
The point is that I have some spare game codes which I sell for crypto.
I have no knowlege of where they were bought, they were donated to me.
I admit that I got them for free and I am selling them for profit, where is the error in that?
Buy from elsewhere if the price is right for you.
