Lagging supply chains are leaving gifters everywhere with nothing to wrap. To ensure no one has to show up to their holiday gathering empty-handed, Heineken has created the IOU. The festive gift box contains six bottles of the Dutch lager with a personalized message that informs recipients that the beers are a placeholder and the real gift is on the way. It also includes a gift card to redeem for additional bottles of Heineken. The promotion is available to all customers over 21 who upload a screenshot of their shipping delay.
