Yesterday I filled up in Whangarie and paid $1.699 a litre for 91 ... why when I look out of my window here do I see 91 selling for $1.999 a litre ?

Does a 34,000 litre fuel tanker really cost $10,000 to drive from Marsdon Point to the Auckland ?

Or is there some extra Auckland tax that the petrol stations have to pay ?

Just curious :-)
