Use combination settings to choose whether your Cart Marshal discount can run alongside product, order, or shipping discounts.
What combinations control
Cart Marshal sends your combination choices to Shopify. Shopify's eligibility and combination rules still determine the final discount result at checkout.
Review rules that can apply together
Review:
- Whether another native discount or app-created discount targets the same products, cart, shipping method, or customer group.
- Whether the rule is automatic or code-based.
- Whether the discount should combine with product, order, and/or shipping discounts.
- Whether the eligibility conditions match the audience and products you intend.
- Whether a qualifying cart and a non-qualifying cart produce the expected result.
Gift with Purchase combinations
Gift with Purchase offers the same product, order, and shipping Combines with choices as other discounts. Both discounts must allow a combination. Multiple Gift with Purchase rules are product discounts, so every gift rule must allow product-discount combinations when you want their managed gifts to become free together.
