Customers might arrive at the order summary page and think that their order has been submitted already. But if they close the browser, they will never receive their order and your company will not receive a completed transaction. At the top of the page, highlight the fact that the order is not complete. Make HIGH-VISIBILITY ACTION BUTTONS (K5) that indicate this by labeling them Complete your order. See Figures F7.1 and F7.2 for a sample order summary page.
