Combining multiple product discount codes

Shopify Discussion
,

Topic summary

Core need: overcome Shopify’s native limitation that only one product-specific discount code can apply (Shopify defaults to the highest-value code) while still relying on discount codes, ideally via an app that consolidates multiple product codes.

Proposed solution: a respondent recommends the app “Stack Discounts Ninja,” which supports stacking/combining multiple discounts via a campaign-based setup and displays them at the line-item level.

Suggested setup steps:

  • Install and enable the app.
  • Optionally hide the widget in settings.
  • Set “Discount display” to “Line items” (to show per-product discounts).
  • Create a campaign with Type: “Reduction.”
  • Add the desired discounts under that campaign, test, then go live.

Notes and status:

  • No alternative apps or methods were provided.
  • No confirmation from the original poster that the solution works for their case; outcome remains unconfirmed/ongoing.
  • Central constraint remains: solution must use discount codes; the suggested app claims to handle this via stacked discounts.

Hello,
I know about Shopify native discount codes limitaions when combining discount codes. I am looking for a solution that can overcome the limitation of inability to combine multiple product discount codes. By default, Shopify only allows one product discount code for a single product (the highest code value is applied). The solution must rely on discount codes. I can imagine some app that creates some consolidated dynamic discount code when it detects an attempt for adding another product discount code, but I am unable to find such app.

Any ideas?

Hello,

Our app Stack Discounts Ninja will do exactly what you need.

For basic requirements you need, after installation, enable the app.

In settings, you can hide the widget (enabled by default).

Also, you can set “Discount display” to Line items.

Then you need to create a campaign with “Type” Reduction.

Add your discounts under that campaign.

Finally, after testing, go live.

Thanks.
