These promotional codes only work on full priced items, so if you already have a discounted item (such as the Double Pack or any sale packs) in your cart, the code won’t redeem.
If you don’t have any discounted items in your cart, email KK2YOU@krispykreme.com.au with the code, a screenshot of your cart, and the error you are receiving when entering the code. Our team will then be able to investigate the issue for you.
