$649.99 - 8GB Apple iPhone next day delivery - Australian Dealer
Keep in mind that the WP & OCAU promo price (+$15.90 for overnight delivery) is for orders placed only via WP or OCAU. Limit is 3 units per customer. You need to whim Syntax Err0r directly (same ID on WP & OCAU). The shop price is still $669.94 inc. delivery.
