Ok so, I had made a deal with him to buy Halo MCC: Complete game. A little back story- I had seen that the game was 40USD. I didnt check steam and instead talked to him. He gave me the cheapest price he could find with the lowest profit margin.
He stayed online for me for a few hours or more so I could set up the vpn etc. He could have not cared and just gone and done the deal. But instead of that, he checked my country (India) and informed me that I could get it for much cheaper here directly from steam. While it was stupidity on my part to not be more vigilant (I love halo :3). He was well aware and sacrificed his profit to provide his customer a better option.
I have had some trade with him earlier also. Dont really remember when. But He is a very kind and good guy. I Vouch for him!
