Quantity breaks take a percentage off a cart line once its quantity reaches a tier, such as 10% off two and 15% off three. The cart shows each line the next tier it can reach, which nudges a shopper to add one more.

## Turn on quantity breaks

1. On **Cart settings**, open **Quantity breaks**.
2. Turn on **Enable quantity breaks**.
3. Under **Quantity tiers**, type each tier as quantity and percent, separated by commas. `2:10,3:15` means 10% off two of a product and 15% off three or more.

4. Select **Save**.

Each cart line shows the next tier it can reach:

The discount is taken off at checkout.

## Choose how breaks behave

- **Skip quantity breaks on cross-sell offers and other discounted products**: on by default, so a break is never spent on a line that is already reduced. Off lets both apply.
- **Let a shopper's discount code take the line from a quantity break**: an order line can carry one product discount. On, if a shopper's code would otherwise be refused because every line already has a discount, the quantity break steps aside so the code works. Free gifts and cross-sell offers keep theirs.
- **Lock the quantity on cross-sell offer lines**: off by default, so a shopper can raise the quantity of a product added from the offers. On, the line shows its quantity without plus and minus, so an offer is taken once. It can still be removed.

## Choose what the app's discounts combine with

**Combine with other discounts** decides whether the app's quantity breaks, gifts and reward goals stack with discounts from elsewhere, such as another app's sale or a shopper's code.

- With nothing ticked, the app's discounts never stack with another. It is the safest choice for your margin. On a cart another discount has already touched, the reward bar, gifts and offers switch off, so the cart never promises what checkout would not give.
- Tick **Order discounts**, **Product discounts** or **Shipping discounts** to let the app's discounts stack on top of that type.

> [!CAUTION]
> Stacking can take more off an order than you intend. Place a test order after changing these.
