Just hunting for a Galaxy Note and came across this from DWI. Seems to be the cheapest around, but I'm not sure of the warranty details. It's stated as "1 year warranty for Samsung", which may not mean Samsung Australia, but I'm guessing Kogan, Topbuy etc have similar warranties.
Anyway, I thought this might help those who are also looking to buy this phone for cheap.
EDIT: most will buy using credit cards or paypal for better security, and i've just realised that these guys have a surcharge for it. Not as good of a deal as i first thought.
With a company motto of "WE DO NOT MAKE LOSS FOR ANY ORDER", anyone buying from DWI must be extremely tight to want to take that risk for the sake of $20 or so.
