Will find out soon enough if it's in USD or AUD.

Ideally, if it's an Australian store the default price should be in AUD. They could always include an option (like on nippon-yasan) where you can choose what currency you want to view the prices in. Of course the exact conversion isn't the same but you get a good enough guesstimate. Dunno if they will do this though.

I like to support local business as well if possible but with more and more official and 3P figures coming out, I'll be more inclined to shop where I wherever find the best price for item + shipping, packing, etc
