Looking to import stuff to Australia from US

Just wondering what some real cheap US online stores that will ship to Australia are?

I'm aware of directron / bestbuy/ outpost / excalibrepc.

Must be able to send via post like USPS as I dont want to pay customs.

Items I'm looking for are x800 pro/gt6800 and OCZ pc4000 gold rev2 .........

Thanks

What makes you think if you use the USPS you wont pay a tariff? The vendor still will be required to ship with a customs slip.

**** from the australian customs site:

"Customs would not collect duty and/or GST where:
* the value of the goods does not exceed $1000 for goods imported by post or $250 for goods imported air/sea cargo, other than by post; and
* the Customs duty and/or GST liability of the goods does not exceed $50."

I think I still have to pay the tariff but there is more chance of not having to if its post not air cargo whatever that means.

The USPS offers Air and cargo(Container aka SEA), one takes roughly a week to get to you, and the other 3-6 weeks. Both are subject to Duty depending on exactly what you referenced to.
