Anyone trying to order from target. I finally got it to go through. Keep 2 windows open, one on the product page and your cart. Spam the Preorder button on the product page, and keep refreshing your cart.
As SOON as you see it in your cart, start trying to checkout, but KEEP spamming the Preorder button. I think I successfully tricked the system into getting another preorder added to cart before it dropped off during purchase.
YMMV, but it worked for me. Good luck everyone!
