For reference, when Marriott has done bonus promos the bonus has been reflected on the Points.com purchase page. However, as you've pointed out, there's a very high chance that any number they show you there could invalidate during the seconds it takes to click the button to confirm the purchase, so I don't know what they'll do here.
