I just tried making a payment from my SG PayPal account to a US Netflix account, it got rejected, they don't accept payment from an overseas PayPal account.
I tried setting up a US PayPal account, using the same browser I use for my SG PayPal account (which may have been the problem, some cookies from the SG account were recognized), it got rejected.
In both cases, my VPN was set to fluke me as a US connection.
I have an option to pay by credit card, but am holding off as I am not sure Netflix will accept an overseas credit card.
Any suggestions?
