I've moved from Canada to Australia.  I go to try and buy a Nexus 4, but it's insisting on showing me prices in the play store (google.com/nexus) for Canadian dollars.  I can only find one country setting in my Google account, and that was in the Calender.  Sadly, that didn't fix it.  Any thoughts?
