Order discounts apply at the cart level. Exclusions let you keep specific collections at full price while still discounting eligible items.

​
Core Concepts

  • Qualifying items: items that satisfy offer conditions
  • Eligible items: qualifying items not in excluded collections
  • Excluded items: items in excluded collections that do not receive discount value

​
Exclusion Behavior Rules

Cart compositionBehavior
All items excludedOffer does not apply
Mix of eligible and excludedOffer applies to eligible subtotal only
Order discount value is calculated from eligible subtotal, not total cart subtotal.

​
Setup Create an Order Discount with Exclusions

1

Create a New Offer

In Atom Commerce, go to Offers → Create New Offer and choose Order Discount.
2

Set Conditions and Discount

Define the qualifying rule and discount value (for example, 10% off order).
3

Add Exclusions

Exclude collections that should never receive this order discount.
4

Review Priority and Stacking

Confirm how this order discount should interact with active item-level discounts.
5

Test Carts and Activate

Test excluded-only, eligible-only, and mixed carts before enabling.

​
Priority and Evaluation Order

Order discounts are evaluated after item-level discounts. Evaluation sequence:
  1. Item discounts
  2. Order discounts
  3. Shipping discounts
When multiple order discounts can apply, priority determines which one runs first. See Offer Priority and Stacking.

​
Edge Cases

​
Gift-card-only carts

Gift cards alone do not satisfy physical-product qualification rules.

​
Items in multiple collections

If an item belongs to any excluded collection, treat it as excluded for this offer.

​
Zero-price items

Zero-price items can qualify by rule, but contribute no discount value.

​
Troubleshooting

​
Discount not applying

  • Confirm at least one eligible physical product is present
  • Confirm cart is not fully excluded
  • Confirm offer is active and in schedule
  • Check for higher-priority conflicts

​
Discount amount is lower than expected

  • Verify eligible subtotal versus total subtotal
  • Confirm exclusion lists are correct
  • Re-test mixed carts with known line items

​
Unexpected stacking behavior

  • Review priority configuration and stacking rules
  • Temporarily isolate offer during testing to validate baseline behavior
