[Trades] Steam Keys

Hey, I've recently received a few keys from a friend of mine who happens to be a huge gamer. I already redeemed codes for these games, and I have spares, so I would like to trade them for other games. So just come here and make an offer, and if I'm interested I'll take it. You can ask for more than one key in exchange for your one key, if your game is better.

My list:

• Dead Island
• Bulletstorm
• Portal 2

Wanted:

• Skyrim
• Battlefield 3
• Modern Warefare 3
• CS:GO
• DOTA 2
• Diablo III
• Make an offer.

 

Dead Island - $2
Portal 2- $2
BulletStorm - $5

 

I know dead island is spammed on this board but I think Portal 2 is worth more. Regardless I'd be willing to trade the corresponding amount of keys, I'd trade a batch of them for a Skyrim key for instance, or etc.

 

I am interested.
Be so kind and post proof that these keys are obtained legally [check this].
Whats the Steamprofile you already activated those keys on?
Do you have any vouches/rep?
