How to block all Shopify discounts code during sales promotion?

Discount compounding becomes a problem when you have promotional sales activities and customers have coupon codes that were previously shared via newsletter or other channels.

You have several options to avoid “double discounting” while you run your promotion:

  • A. Manually deactivate all coupon codes and reactive once your promo is finished.
    • This can be very time consuming if you have a high number of active coupons.


  • B. Create your promotion with a coupon code – This way the customer will be able to only use 1 coupon code.
    • Example: Instead of applying a 20% strike-through price, also known as sale price, you can create a coupon that provides a 20% discount on specific products. The downside here is that you don’t make the promo visible automatically in the price which will affect your promotion conversion rate.


  • C. Create a Shopify script that deactivates all coupon codes temporarily. See example below for code. (For Shopify Plus only)

You can install the official Shopify scripts app here (it only works for Shopify Plus plans)
