I'd love to know if there's a way to do this.
I'm in Australia and the only way I have found to buy off the Sony ebook store is incredibly convoluted. Right now, I need to:
1. Buy virtual credit card from
http://www.unlinq.com/vc_faq.html their cards have a local US adddress and Sony's AVS check lets them through.
2. Only way to fund these virtual cards seems to be buying these "egold" type online currencies so I end up buying a ton of pecunix.com currency.
All up this process adds around 15% extra in processing fees, and is really really roundabout and annoying.
What's more annoying is that Sony explicitly check AVS on credit cards now so using my own cards don't work since they deny non US (or presumably non-UK) addresses. They also deny cards that don't respond to AVS queries, heh.
I really don't understand why they make it so hard for people to make them money
