Why do I have to pay E Bays exorbitant GSP shipping costs wich they say covers customs duty and everything else ? when here in NZ we have no Customs Duty Fees to pay on anything under a $1000 and what is everythibg else .

Everything just turns up in the letter box.Some purchases can gather NZ$ 30 in GSP shipping for 1 card

I have asked sellers if they will just send it normal shipping but thats a no no might miss out .
I realise that they are protecting themselves but there must be a way.

Would BIN cover it or is that also covered by E Bay shipping too Although I do not purchase much now, but in todays enviroment anything that is cheaper would be appreciated
