# Additional discounts after product savings

> Apply another percentage to selected merchandise after product discounts, and understand combination permissions and independent campaign eligibility.

Additional discounts run as order discounts: product savings apply first, then another percentage reduces the discounted amount of the selected merchandise. Use this for an extra 5% for social customers during a Black Friday sale.

## Key settings

1. Add **折后额外折扣** (Additional discount) and enter `5` for the percentage.
2. Select merchandise eligible for the extra savings. If campaign scopes differ, use their intersection.
3. Configure this campaign's customer eligibility, tags, and other thresholds.
4. Keep **可与商品折扣叠加** (Combine with product discounts) checked.
5. The product campaign must also allow **可与订单折扣叠加** (Combine with order discounts).
6. Align both campaigns' schedules, scopes, and conditions, then test checkout.

## Calculation

A price of 100 becomes 80 after 20% off, then 76 after another 5%. The total savings are 24, not 25. Enter `5` in the additional rule, not `24`.

> [!WARNING]
>
> This rule does not check whether another campaign actually awarded a discount. When its own conditions pass, it can apply 5% by itself even if the product campaign is paused, ineligible, or replaced.

This is not a dependency on another campaign. To restrict the extra offer to customers in both Black Friday and social groups, use two tag conditions and require all conditions.
