I have....... I managed to get two titles that way. But I live in Australia, and if the DVDs aren't released in the country at all, then I can't buy online in Australian dollars.
I have to import from America, online. It costs me an arm and a leg, with shipping costs, money orders and lastly the crappy exchange rate. The AUS dollar being only worth 70 or so US cents. (on a good day in the stock market)
So yeah....... sorry for straying off topic there guys
