Well, there's the million dollar catch isn't it...?! I pay $15.99 US for magazines now that cost about £5.99 GBP. I don't know how the conversion works out going to Australia, but I imagine a U.S printing would go for a similar conversion of shipped. One way to avoid this would be to digitally distribute it to a print house in Australia and have it printed domestically there. I wish some of the Brit Rags would do that here.
