Multiple item purchases are highly encouraged, discounted shipping rate will be determined at the end of auctions. This rate will be depending on the number of items, total weight and size. Buyer must add $15 for USPS Registered International Mail service, it will be used for any oversea purchase over $100. USPS Express Mail service will be used for any purchase over $400, buyer pays only half of the cost at $25.

***Note to buyer from Mainland China. Due to recent heavy losses for shipments to this area. Buyer in China must select one of the three shipping options:
1. USPS International Priority Flat Mail Service with tracking up to 4lb weight = $31.00
2. USPS International Registered Mail Service = $15 plus shipping fee
3. Drop off service within China, I will visit China multiple times each year, shipping cost depends on the value and weight of the shipment. This is probably the cheapest shipping cost.  
Please provide your address in Chinese and phone number for option 3. Thanks for your understanding!
