Why do I have to pay 2 times the shipping fee?
Because the item is bought from Japan, so there will be 2 different shipping fees: :- Domestic shipping fee (from the seller's address to the Janbox warehouse in Japan).
- International shipping fee (from Janbox warehouse to your address).
The Domestic shipping fee will be included in the product price when the bid is won or placed an order. And you will pay at the first charge. In some cases, domestic shipping is charged at the second charge due to the seller's choice of COD shipping.
