You may cancel an order any time before the item is delivered to the international shipping carrier. Due to unpredictable nature of international shipping, once an item is handed over to a shipping carrier, it's difficult for us to intercept it. Moreover, international shipping is expensive and involves many customs fees. Therefore, we recommend you not to cancel the order after we deliver an item to the carrier. Otherwise, you'll need to pay round-trip shipping fees on the item and possibly customs duties and fees.
