I want to be able to add keys to my inventory !!

you can't do that

exploitable keys = bad items to trade with

You want to sell your Indie Bundle keys like Steam gifts, don't you?

Thats why we'll never get this feature.

Way back when inventory was first announced, some Valve employee said they were gonna do that.

I'm pretty sure that with these endless Indie Gala bundles and reddit key giveaways, they've figured out it's not a good idea.

The computer says 'no'

step 1: Open TF2

step 2: Go to Mann Co. store

step 3: purchase key

step 4: open house door

step 5: lock door with said key.

Cause if they do that, a lot of abuse would be imminent and Steam would lose a lot of money. Quite a few retail games do have steam redeemable keys are are WAY cheaper than the same thing on steam store.

Why do you complain here?Go on the Steam forums and complain there,we can do nothing about it.

IF this would be implemented, then you would probably be the only one who does this and you can have a lot of profit because no-one else will be buying indie bundles and then turn the keys into tradeable games and it will not devalue those games at all.
