We offer Free Upgrade to Standard shipping for over US$ 50 purchases.
You can choose FREE Economy Shipping (No Tracking Japan Post) ,Standard Shipping (Registered mail with Tracking Japan Post) or Expedited Shipping (FedEx International Priority ). The differences between Economy and Standard are the tracking service and insurance. Otherwise those are fundamentally same.
You can save shipping fees when you buy multiple items, as I do not charge shipping fees for additional items.
For Expedited Shipping, it will take about 48 hours to USA in average.
