I have been watching these for a while and this may be a price error given that the 11.11 sale price is about $12 more. Cheapest on EBay is $63 and they are around $80 in Bricks and Mortar stores. To test if it was an error I have ordered one and have just got the shipping notification so it looks like it will be fulfilled. Comes with AU plug.
