Although the customer has to notify the seller customer code written in the

surface of a single, but some sellers will forget the customer code written on it,

when we receive the goods,we don't know the parcel belong to which customer,

so we need check out from the doc which  customer send to us

that is the  reason we require customer to send the courier no to us after custome finish shopping goods.

      If customer send all the courier no to us, we will check courier no which wirte

down in the customer code record, if we don’t find the courier no which customer

 offer, will find it from the uncertain customer code record. (we have a doc for

 uncertain customer code reocord)

        In order to prevent confusion, customer must be buying all the goods, get all

courier no, then send it to us via email.
