Estimate weight and volume
Shoes, jackets, and bags can raise shipping cost faster than light shirts or accessories. Look at actual warehouse weight when possible and be careful with bulky packaging.
Choose a line for the parcel, not the product
Shipping line choice depends on destination, parcel size, delivery expectation, and risk tolerance. The best route for one haul may not be best for another.
Keep timing realistic
Tracking updates can move slowly. Build your haul plan with enough time for seller shipping, warehouse processing, parcel submission, and customs handling.
