EBAY KEY METHOD

1)- First, search for a gamkey you wanna buy.

2)- Now you buy it with Paypal and wait for the key arrives, activate it.

3)- Go to paypal and make a refund. Then Escalate dispute and wait for your money 
coming back to you.

4)- I would recommend to buy the keys from G2A's Ebay. They never respond.

5)- Enjoy your free game!
