A store owner reports that automatic discount codes display correctly in the shopping cart but disappear when customers proceed to checkout. This issue started recently, despite all discount settings being configured correctly and the feature working previously.
Suggested troubleshooting steps:
Disable apps that may interfere with discounts (upsell apps, bundle apps, etc.) and test again
Verify if the store recently upgraded to Shopify Plus, as automatic discounts may not apply properly in custom checkouts
Check for recent theme updates that could be causing conflicts
The issue appears to be a conflict between Shopify’s automatic discount system and either a theme update, third-party app, or checkout configuration change. The problem remains unresolved and requires systematic testing to identify the root cause.

I have several automatic discount codes and they are all being added in the shopping cart. However, when checking out, the discounts dissapear.. Is there a way to solve this prohblem or to find the problem at least?
I have checked all setting for the automatic discount codes and they are right.
It worked before, but since a few days they’re not showing anymore at checkout.
Hey @HOUSEGV I think it like a conflict between Shopify’s automatic discount system and either a recent theme update, an app, or checkout settings.
You can try disabling all apps that might interfere with discounts (like upsell or bundle apps) and test again. Also, check if your store has recently switched to Shopify Plus, as automatic discounts don’t always apply in custom checkouts.
