今天上Amazon試下訂單,可是有幾點疑問想請教....

郵寄方式我是選
Standard International Shipping (Averages 11-21 days)
這樣約多少天會收到?

Subtotal of Items: $76.46
Shipping & Handling: $9.96 <<-----是如何算出來的?
(我看說明Per Shipment 3.99,Per Item 1.99 ?_?)
Total Before Tax: $86.42
Tax: $0.00

Total for this Address: $86.42

以上疑問還請前輩不吝指教謝謝~
