1) Pls find attached Air Way Bill.
2) About the actual air freight.
All goods = 18 cartons = 113kgs = 0.86 CBM
Chargeable freight = 0.86 CBM/0.006 = 143 kgs
That means we have paid forwarder = US$ 489
You have paid us = US$ 310
So you still have to pay us = $ 489 - $ 310 = $ 179
Pls pay this US$ 179 to us in our next order.
I feel so sorry to bring you troubles, and I would like to try my best to apply a discount for your next order. Hope you can understand.
3) I will send you the certificate of origin (FORM E) by courier in one or two days. It's not together with the goods.
4) I have sent a pen and a male belt together with this order for you and your manager, pls find and check it.
