The trade didn't go well for me but he delivered.
We agreed upon the games to trade but my key was duplicate. He asked for another game and the two keys I provided for it were duplicated. At the end I gave him a working key. I was ashamed and was all about to be blamed, but he behaved politely.
I asked the guy not to leave +rep on my profile as that +1 would be an unfair successful trade count.
+rep. Fast and smooth trade. Very friendly and generous trader as well. Thanks! :)
+Rep Smooth trader, Polite and reliable they went first and we traded their copy of Californium steam key for my Kelvin and the Infamous Machine steam key.
Everything went well and would highly recommend them, Take care and thanks again for the trade.
Genuinely a good guy! It's always nice meeting someone like you. Thank you for the pleasant trade and wishing you a great day :)
