# Quantity scenario: 10% off at 2, 20% off at 4

> Configure two product quantity tiers and verify eligible counts, out-of-scope products, and the higher qualifying offer.

Use a product tier to offer 10% off at 2 selected collection items and 20% off at 4. Each eligible item costs 60; only that collection receives savings.

## Example settings

| Setting | Example value |
| - | - |
| Rule | Tiered discount |
| Discount target | Product discount |
| Tier basis | Quantity |
| Tier 1 | Threshold 2; percentage 10 |
| Tier 2 | Threshold 4; percentage 20 |
| Scope | Specific collection |

## Configuration steps

1. Create an automatic discount and set customer eligibility, markets, and dates.
2. Add **阶梯折扣** (Tiered discount), choose **商品折扣** (Product discount) and **按件数** (Quantity).
3. Add tiers from low to high: `2 / 10%` and `4 / 20%`.
4. Select the actual collection, save a draft, then activate.

## Checkout acceptance tests

| Test | Expected result |
| - | - |
| 1 collection item | No tier discount |
| 2 collection items; subtotal 120 | Save 12 |
| 3 collection items; subtotal 180 | Save 18 |
| 4 collection items; subtotal 240 | Save 48 |
| 1 eligible + 1 out-of-scope item | Does not meet the 2-item collection threshold |

The higher tier does not add its percentage to the lower tier. See [tiered discounts](https://discount.xrtotech.com/en/features/tiered-discount.md) for amount-based tiers and order targets.
