You can use credits to offset your delivery fee (1 Buy&Ship credit equals 1 HK dollar). If the credits are insufficient for offsetting the fee, you need to make up the difference.
For bulk shipment, you can only use the credits in your account purchased before the order is created in our Hong Kong warehouse to offset the delivery fee.
For single shipment, you are advised to purchase credits before your shipment is sent out from our overseas warehouse. An order will be created automatically when the shipment arrives at our local warehouse, and credits in your account will be deducted automatically to offset the delivery fee at the same time.
