[H]Retail Key Metro 2033 [W] Anything giftable that I can just keep in my inventory, lol

I'm going to end up losing the retail key if I don't get rid of it. I purchased the Amazon THQ bundle like 2 weeks ago. I already had Metro 2033 so the retail key wouldn't allow me to put it as a gift in my inventory.

Anyways, shoot me an offer and we can strike a deal.

I have faith that you wont scam me because you can get the serial key from the humble bundle for a buck, so it shouldn't be worth your time to scam me, but if you happen to have something you want to get rid of that's just sitting in your inventory, maybe you want a retail key of Metro for it!

(If we come to an agreement, I will give the retail key before you trade me whatever game)
