What this type does
Combine discount builds one automatic or coded promotion while designing different kinds of savings separately:
Add only the slices you need. A gift and Buy X Get Y cannot be used at the same time. A gift runs only as an automatic discount and can’t be used with a code. Product and order tabs can use volume and tier breaks.
When you publish the promotion as Discount code, customers enter one code at checkout. That code applies every tab you configured whenever the shared eligibility rules pass. A gift tab is not available on a discount code — use Automatic for a gift.
The picker label shows Combine discount. Reporting labels in Shopify Admin may resemble other automatic Smarty-built discounts depending on storefront context.
Why merchants use it
- One code, full stack: coded campaigns stay simple for shoppers — the same redemption unlocks product, cart, and shipping savings in one go (only the tabs you enabled).
- Coordinate multiple savings so they share one eligibility posture and one purchase-type choice (subscriptions vs one‑time).
- Reduce configuration drift versus maintaining three independent discounts with nearly identical qualifiers.
- Ship cohesive campaigns whose product, cart, and fulfilment tiers were authored together.
Screen structure (usual order)
- What this discount includes — Add savings opens product (up to three), Mix & match, Buy X Get Y or a gift (not both), order, or shipping. Remove a part from the options in its tab.
- Each tab — the same value and rules as that standalone discount type.
- Stack and checkout message — Stack with other savings in this discount is on by default. Turn it off to skip items an earlier product, Mix & match, Buy X Get Y, or gift tab already saves on. Stacking is applied in tab order. Custom checkout message is optional; leave it empty to use the discount title.
- How savings apply — optional Maximum total discount. It applies per order and doesn’t count shipping. Shipping keeps its amount. Product, Mix & match, Buy X Get Y, and order share what is left.
- Purchase type — one choice for the whole discount: Subscription, One-time purchase, or Both.
- Eligibility for discount — one rule that must pass before any tab applies.
- Shared extras — method (automatic, one code, or bulk codes), combinations, dates, and recurring limits. See Features.
