It is several weeks ago now so I am a bit hazy on the details of the individual parcels now but I will give you what details I can remember.
The return address on one parcel was the sellers own address...the others I don't remember.
One parcel had no Customs form at all, which I thought a bit strange. Two parcels had individual Customs forms filled in by hand.
None of them had labels stuck over labels and no mention of Erlanger in sight.
They all had postage labels stuck on them with the USPS service used and $ amount paid.....and very clearly the words Pitney Bowes.
The first two were sent by Priority Mail and were very slow getting here....the third one came Priority Express and was almost as slow.
From that it seems that the GSP was not involved at all in the shipping. Pitney Bowes is famous for postage meters, USPS labels are likely to have been paid for online using a Pitney Bowes app, no connection to the GSP except coincidence and it being another aspect of PB's business.
GSP sent items do not have individualk customs forms, the seller sends to Erlanger as they would to New York, no customs form.
There is no need for one as the prepaid money covers the import clearance of the items as a bulk shipment. \items sent as yours were were only not charged again for import taxes because of the high import tax threshold Australia, pretty well uniquely in the world, enjoys.
It is probable that the item sent with no customs form was simply incompetence piled on incompetence by the seller.
All you have said supports my original contention. The GSP does not use USPS to do the international shipping and anything that arrives with USPS mailing labels through AusPost has been mis-sent by the seller.
The level or misunderstanding and general **bleep**-up shown by GSP users is very evident on the USA International Trading board and the Canadian Buyer Cental board.
It really seems pretty calm over here.
