Bro, as a fellow aussie. Just pay the dollars.. its worth it. pccg and auspcmarket, arent really looking to expand ranges on a few random dudes authority. EK, can get you the board you want, at the best price. it only seems fitting to pay a fat chunk ( i know nearly half) on postage.. to be fair, its a fkn long way..
So the way I offset the postage.. was buy more crap that would have cost me postage. Ie sweet leopold travel case.. highly recommend, esp if commuting. and random keycaps.
