The estimated shipping cost is calculated based on the weight, volume, and required packaging materials of the package before it is packaged. This weight may differ from the actual shipping cost.
After paying the shipping fee, the Onebuy operation center will complete the packaging accordingly. The final shipping fee will be calculated based on the final weight of the packaged goods, and then any excess or shortfall will be refunded based on the estimated shipping fee paid by the user.
It is recommended to submit the "Preview Package" value-added service, which can obtain accurate information on the actual weight and volume weight of the package before the official shipment, in order to obtain the correct shipping amount and avoid estimated shipping cost differences.
