They’ve been running 40% off until what was supposed to be yesterday. For me it’s showing as $999 US on the product page and still $999 when I add to cart. Perhaps you’ve just got an old product page cached still showing the sale price (which was $611)
Oops we were replying at the same time. But as I said, that looks exactly like what’s going on, the AU product page is still showing the sale price that has ended.
