I signed up to netflix for the 1 month trial by adding my Westpac Visa to a US paypal account.
That worked for the trial but now that the trial month is over, netflix wont renew the subscription through Paypal with that card attached.
I have a US iTunes account too but that has the same problem with my NZ based cards.
I have also tried all the tricks I have seen in relation to changing postcode / billing addresses. ( I had been using a youshop address and this worked at first with the paypal signup )
It seems like some people get lucky with the right bank / card type.
Please help - last night was torture without Netlfix!
