We recommend reviewing Combining Discounty with Other Discounts first to understand how Discounty interacts with third-party or Shopify-native discounts.
Shopify and Discounty discounts can stack unintentionally — especially when using Price Rule campaigns, which modify both the product’s main price and compare-at price. Because these campaigns change the core product price, there’s no native way to block other Shopify discounts from applying at the same time.
However, there is a workaround in specific scenarios.
You can prevent Shopify discount codes from stacking if you're running product-level Discounty campaigns (not storewide). You can use a smart (automated) collection in Shopify to exclude products that are already discounted by Discounty. This method prevents your Shopify discount codes from applying to items that have a compare-at price set by a Discounty campaign.
Why this works:
Shopify will not apply a discount code to products not included in the associated collection. So any product actively discounted by Discounty (i.e., has a Compare-at price) will be excluded, and Shopify won’t apply additional discounts.
⚠️ Limitations: This won’t work for storewide campaigns
If your Discounty campaign applies a sitewide price reduction using a Price Rule (e.g., 20% off everything), stacking cannot be prevented with this method.
Step 1: Create a smart collection that excludes Discounty-discounted products
In Shopify Admin, go to Products > Collections.
Click Create collection.
Set the collection type to Smart.
Add a condition:
Compare-at price → is empty
This filters out any products that Discounty has applied a price rule to (since Discounty sets a compare-at price).
Click Save.
Note: Shopify collections work at the product level, not the variant level. If you need variant-level filtering, Shopify currently doesn't support this with smart collections.
Step 2: Apply a Shopify discount to that collection
In Shopify Admin, go to Discounts > Create discount.
Choose Amount off products.
Under “Applies to,” select the custom collection you created in Step 1.
Set your discount value (e.g. $10 off or 20% off).
Click Save.
This ensures the Shopify discount only applies to non-discounted items (i.e., those without a compare-at price), avoiding overlap with Discounty’s Price rule campaign logic.
Why this works
Discounty sets a compare-at price when applying a Price rule campaign.
Your Shopify discount targets only products without a compare-at price.
This separation avoids stacking discounts on the same product.
