~$87 cheaper than buying it local, make sure you change currency to USD before placing order.
*** Note ***
$334.79 is the price when using my 28 Degrees card with no conversion rate fees or international fees. Purchasing under AU currency comes to $347.10 including delivery.
You would still be better off purchasing under USD and paying the small conversion fee of $2 or $3 from your bank.
Just keep in mind that while Amazon may cover return shipping because they're awesome, it will take weeks and months to get it back if you do end up getting a bad unit that's either dead on arrival or dies shortly after.
