Places to look for between tonight and tomorrow just off the top of my head:
TheNextDoor.Fr will have it randomly between 1:00AM - 8:00AM.

Did you try purchasing a giftcard? Adidas's payment processor isn't the best, especially since everyone is trying to check out at the same time. You can try purchasing giftcards after you cart since you have 10 mins to check out (Most you can put on a giftcard is 100$ but you can stack them).
