You’ve probably run into this: a customer adds products to their cart, enters a discount code for 15% off, but then abandons the order when they realize shipping still costs $9.95. Or worse - they need to hunt for another code to get free shipping, and Shopify won’t let them stack it. The result? Lost sales, frustrated customers, and messy marketing campaigns.
Shopify’s One discount for multiple savings feature - introduced in the Summer ’25 Edition - finally solves this by letting you combine product discounts, order-level savings, and shipping offers into a single, clean code. No more coupon clutter. No more “Which code do I use?” at checkout. Just one promotion, multiple benefits, higher conversions.
If you implement this feature with the right discount app, you can simplify your promotions, reduce abandoned checkouts, and run more profitable campaigns — all without compromising the customer experience.
What is “One discount for multiple savings”?
Traditionally, Shopify discounts were siloed: product discounts, order-level discounts, and shipping discounts often required separate rules or separate apps/scripts. The Summer 2025 release formalized a new approach: using the Discount Function API a single discount (code or automatic) can now return operations that affect cart lines (products), order subtotal, and shipping rates all at once. That means one code can, for example, give 20% off selected items and free shipping over a threshold - without making customers enter multiple codes or stacking weirdness.
Developer-facing note: Shopify’s Discount Function API unifies former separate product/order/shipping function types, so apps can implement one “function” that outputs multiple discount operations in a single pass at checkout. That’s the technical enabler behind the UX improvement.
Benefits of one discount that does multiple savings
Don’t be starry-eyed - these are benefits, not a free lunch. Use them deliberately.
Better customer experience
-
Fewer coupon codes to remember = less friction at checkout. Customers don’t have to wonder whether a code covers shipping or product. (Real win.)
Cleaner marketing and tracking
-
One campaign → one code → simpler UTM/attribution and easier reporting. You can test an offer without juggling three promo assets.
Smarter promos (and higher conversion potential)
-
Combine incentives to nudge behavior: e.g., a product discount + free shipping at a $75 threshold converts better than either incentive alone.
Operational simplicity for POS and omnichannel
-
The Summer ’25 notes call out POS improvements too - a single discount can apply in retail checkout flows where it helps staff and speeds up lines. (Yes, this matters for real-world stores.)
Margin control - if you plan for it
-
You can design composite discounts that cap or prorate savings the way you want (but only if your discount app/function gives you that granularity).

3️⃣ Display settings:
Configure countdown timer, widget design, pop-up suggestions, and notice in cart - just like you normally do with other discount types.
This isn’t just another discount. It’s the ultimate deal-stacking machine that turns any sale into a Mega Sale.
Best practices for using One discount for multiple savings in Shopify
1. Keep the offer simple and clear
If customers need a chart to understand your deal, you’ve already lost them. Summarize in one sentence: “20% off all backpacks + free shipping over $50.”
2. Set thresholds strategically
Don’t give away shipping on $10 orders unless it’s intentional. Use minimum spend levels that increase average order value without scaring buyers off.
3. Test on all channels
Shopify POS and online store sometimes handle discounts differently - run test checkouts in both environments before launching.
4. Avoid stacking chaos
Even with this feature, decide whether your unified discount should stack with other promos. Many brands disable stacking to protect margins.
5. Measure what matters
Track redemption rate, average order value change, and margin impact separately for each discount component (product, order, shipping).
6. Time-limit your campaigns
Scarcity still works. Limited-time unified discounts can create urgency and focus your customers’ attention.
7. Always run a rollback plan
Have the ability to disable the discount instantly in case of bugs, misuse, or sudden inventory shortages.
Final thoughts
Shopify’s One discount for multiple savings isn’t just another shiny feature - it’s a structural change to how promotions can work in your store. By merging product, order, and shipping discounts into one code, you cut checkout friction, present a cleaner brand experience, and give your marketing campaigns more punch.
