Q: During seasonal transitions, the store clears out off-season items. How can we set promotional items to automatically and consistently participate in whole-order discounts or customer default discounts?
A: Follow the steps below to operate via MC Seller.
Steps: MC Seller " Order" page → "°°°" in the lower left corner → Adjustment (%) → Enable "Discount on promotional items" → Click the "🔐" button to lock the promotional items to permanently select them for the whole-order discount (%)

Friendly reminder
Once the promotional item is locked with the "🔐" button, it will be permanently locked. If you want to cancel, you need to tap to unlock it again.
