As in you'll give away a copy of Dota 2 in exchange for two copies of Portal 2? If so I wish you luck, considering Dota 2 has basically zero value.

In addition to this, Dota 2 is worth peanuts these days. Valve, over the past few weeks, have given out thousands upon thousands of Dota 2 invites - with many recipients giving away invites for free. Along with that, Dota 2 is set to be a F2P game upon full release. The price you see for Dota 2 on the Steam Store is, really, the price for the items that are bundled.
