App Introduction

When a cart contains promotional products, block discount codes and the discount input field. DCB prevents customers from applying discount codes to already discounted items (those with a compare-at price). By blocking additional discounts on already reduced products, it ensures your promotional campaigns remain profitable. Note: When a cart contains promotional products, it will block discounts for the entire order! Due to technical limitations, free shipping codes still work in Basic, Advanced, and Grow stores.
