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. Smarty caps the layout at three tabs and does not duplicate types (at most one Product, Order, or Shipping slot).
When you publish the promotion as Discount code, customers enter one code at checkout. That single code applies all slices you configured (every enabled Product, Order, and Shipping tab together) whenever the shared eligibility rules pass — you never assign a separate code per tab or per discount type.
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)
- Discount components — tab strip labelled Discount components. Add discount adds another slot when one of Product / Order / Shipping is unused (up to three tabs total).
- Purchase type — global control for recurring vs one‑time purchases (Subscription, One-time purchase, or Both) after configuring components.
- Per‑tab editors — only the slice you chose for that tab: product value + apply rules / order exclusions / shipping selectors, consistent with each standalone type guide.
- Eligibility for discount — a single nested rule builder that must pass before any slice applies.
- Shared extras elsewhere in Smarty — method (automatic vs code vs bulk batches), combinations, caps, calendars, recurring guardrails. See Features. With Discount code, that method uses one code for every enabled Combine tab together.
