Games On Demand - May 1, 2010
Ah, Australia. Your beautiful beaches, your friendly people. Your gouging bloodsuckers.
According to xe.com, on the 1st of May, 2010, the exchange rate for AUD to USD was 1.00AUD = 0.924100USD. So let's see what that means. All info was taken from the US and AU version of the xbox live marketplace on the web, not the console. US prices are in USD, AU prices are in AUD with the US equivalent in brackets.
I didn't do the Xbox originals but Microsoft charges The AUS $50 (46.2050) for the 3000 points card on their site.
Steam has to comply to this sort of stuff too. It's so fun.
