Nintendo Handheld Console 3DS XL (red/black) shipped for $170 by Amazon UK
Amazon UK have the Nintendo Handheld Console 3DS XL in red/black for a very good price of around $170 including delivery to Australia.
Looking locally for the same console I found it listed at JB Hifi for $239, Gamesmen.com,au for $246.90, MWave.com.au for $248.95, and also at Big W for $278 (all prices inclusive of shipping).
Note, when you click on the link and arrive at Amazon´s page listing the console, the price in GBP is 119.00. You need to continue and click through the part where you say you want it shipped to Australia so that it calculates shipping - at which point the VAT comes off and you´ll get it for the price of 107.65 GBP (which works out to around $170 AUD).
