Updated List
Now with Coupons!
I'll happily swap them for any two normal cards in my want list.

Have:
Coupons
75% off Prime World: Defenders, expires Aug 04
75% off Portal 2 expires Aug 13 Taken!

Want:
Nothing really, just does anyone want these? I didn't really know where else to put this. Got them from badge crafting and really not interested in either game, so if you want them they're yours.

I'd really appreciate the Portal 2 coupon, if you don't mind :) My birthday's the 5th, so I'll hopefully come into money by then to get it.

Coupons :

Triple Town -50% (expires in few hours)
Starvoid -66% (expires in few hours)
No Time to Explain -50% (expires in day and few hours)

Either for free or for cards, your choice.

That No Time to Explain coupon can't be used because the game is currently on a weekly sale.

I have to say, this trading card system is utterly ingenious on Valve's part. Why, you may ask? Well, I managed to sell a single trading card (which usually goes for around 3 cents) for a whopping $52.18, and only two weeks after I put it on the market. Since I can turn those cards into a lot of money, there's now a very solid reason for me to buy games on Steam rather than other sites (such as GOG) if it means I could get more rare cards that I could then sell off for a stupid amount of money.

This has to be the first customer loyalty program that's ever garnered so much as a second glance from me. All in all, I'm most impressed.

Did this card suddenly go out of print or something?

Nope. It was the emoticon for participating in the beta. You can buy them from 3 cents each.

Looking for Rise of the Triad cards.

I'm looking for G-man Half-Life card and I can give you Alyx for it (it's for my friend).

I can help you with that, please accept my friend request on steam ;)

Done and thank you.

I have two spare Left 4 Dead 2 Charger cards, will exchange for two other L4D2 cards beside Charger and Witch.
