Still trying to find one myself. Be willing to pay an extra $50 over cost and shipping if anyone has extras or one they don't want. Prefer a 32GB but wouldn't mind the 16GB either.
I've picked up at least a dozen games from them and I've never had a problem with a single one. That's a really good deal on Halo Wars and if I didn't just pick it up a few weeks ago I would have jumped on it.
