Promotion is up on Amazon

There is no way to receive a code from that page specifically, as in purchasing a 'qualifying item', as you do need to go into whatever item it is's page and look for the promotion icon. But that is the place you would get the actual Mog Station redeemable code from.

Thank you for this link! I was worried the vague "6 in-game items" mentioned on Amazon would be something stupid like, "1. Butler Shoes, 2. Butler Pants, etc." It's nice to see official confirmation that we'll be getting all the major items in one go.
