I added a $50 Amazon gift card to my Amazon US account several months before they cracked down on Australians accessing the US site after the GST changes. Seems you can't buy much from the US site anymore - I tried to buy a Kindle book yesterday from the US site and it forced me to the AU site where I can't use my gift credit.
I'm wondering if I can request Amazon transfer my credit to my AU account. Has anyone had success with this?
Have you asked Amazon?
