That's good thinking with switching to the US account for it. I would do the same thing if I were you. I only buy the deluxe editions when I think there's a nice slice of bonus aesthetic content that's worth the extra 10 bucks. It's probably a waste of money, but it beats the curiosity that might eat away at me if I have to waste money later for something that might look kinda cool to wear through my first play through, you know? Plus, I usually don't mind spending a bit extra if the developers deserve it. In this case, I want them to have my money.
