Promotional codes from Dunnes Stores are applied during the checkout process, on the Shopping Bag screen. Promotional codes can only be used once and not in conjunction with any other offers or discounts, unless stated otherwise. Promotional codes must also be used during the checkout process and cannot be applied or redeemed once a transaction is complete.
To apply a promotional code, click or tap the Shopping Bag icon on the top right-hand side of the screen. Underneath Subtotal, click or tap on Do you have a promotional code?, enter the promotional code exactly and click or tap Apply.
