Well from various dealings if it's cheap aftershave, cologne ect dealing through yesasia's aussie portal, yesstyle, tends to be about 40 - 50 % cheaper than aussie retail, rest of their stuff is relatively overpriced but and some is downright tacky. Be aware they use some pretty dodgy couriers at times so stuff can either be a few days or a few weeks depending on that. For clothing you might want to look at some of the american retailers like jcpenney ect as some of them do actually ship here and tend to be about 50 - 75 % cheaper than aussie retail (e.g. - looking at jackets yesterday, $500 in Perth, same thing available for $80 online). For games ect it's a bit more difficult den as there are some pieces of equipment with region locks and some new DS games have hardware checks that freeze the game randomly if modified. If you're looking for genuine try some of the UK online retailers and buy PAL games as these will wwork in DS consoles sold here(most are there). They do cut shipping costs and are cheap upfront (i.e - mario kart DS goes for $50 here, $15 over there and often less)
that aside this was the best price i found, $199 usd with free shipping:
