Price per set is USD25.84 but you can get 2 sets for the same DHL courier shipping price of USD (to Sydney 2000) of USD19.75.
Breakdown is as follows:
Subtotal: $51.68 (2 Sets)
Shipping: $19.75 (DHL Express)
Duties & Taxes: $7.14 (AU GST)
TOTAL: $78.57 (USD)
These awesome (IMHO) little controllers carry a local RRP of $79.95 and the best price I've been able to find is Amazon AU at $62.76 delivered per set. My first couple of sets were purchased while I was in the USA at USD45 per set (incl state taxes).
To be clear, I'm suggesting these are a good deal at AUD115 delivered for TWO (2) sets via DHL courier versus $125.52 or $159.90 delivered via USPS/AusPost snail mail. If you only need/want one set, just go with Amazon AU and wait for the global postal system to recover from the Santa rush.
EDIT 11.20am AEDT — Stock has gone from "IN STOCK" to "MORE ON THE WAY" which means they are honouring this price for backorders. Well-played OzBargain, well-played.
I just ordered four sets. Details as follows (the DHL rate is pretty sweet).
Subtotal: $103.36 (4 sets)

You Pay: $141.21 (~AUD51.25 per set)
