The product card/cart shows the Korean listing price and an estimated USD goods/order amount using K-Shippify rate logic. The estimate must be fresh before it can be used for saved-card authorization.
Goods/order automatic charging is allowed only when the final USD amount is no more than +10% above the fresh USD estimate snapshot.
A goods estimate is valid for 24 hours or until item details, quantity, destination/address, store, FX/rate snapshot, pricing/config, supported-store, prohibited/restricted-items, blocked-destination/sanctions, or checkout rules change.
