1.per shipment 同 per items 即係點
根據 http://www.amazon.com/gp/help/customer/display.html/ref=hp_rel_topic?ie=UTF8&nodeId=596188
Expedited Shipping Rates to Asia & Pacific Islands
Product Category Per Shipment Per Item Books, VHS videotapes $13.99 $5.99* CDs, DVDs, Music Cassettes, Vinyl $13.99 $3.99* **Jewelry, Watches, Clothing Items, Shoes, Baby $13.99 $4.99 **Automotive, Computers, Electronics, Home, Personal Care, Kitchen, Outdoor Living, Sports, Tools, Toys $13.99 $2.49/lb Any combination of the above items $13.99 As above
例如
同一個賣家買三樣嘢，for amazon，個shipping 係 2.49X3? 定係一筆過13.99?
for 其他商鋪，個shipping=?
如果去兩個唔同嘅賣家各自買唔同數量嘅嘢，又點計呢？
有人話買多幾樣嘢，per item嘅shipping平d，即係點呢？果幾樣有combination或者唔係combination，計法又應該點做？
2.兌換率係睇credit card 定係amazon有自己嘅匯率？

同一個賣家買三樣嘢，for amazon，個shipping 係 4.99X3? 定係一筆過13.99?
更新2:
combination = $2.49 x 磅數？
更新3:
如果係低過一磅，都當一磅計？
