Best Buy had early access for their elite members starting today, and since they'll only ship it to you, and I will be away until next week, it seemed to be the most sensible route to go. So, I went to bite the bullet, and of course Chase's fraud systems are a bit... particular. So I'm on the phone with Chase security now so that I can get the charge to go through.
