Yes it is.
There have been several Q's today regarding some nefarious plan behind the price drops.
One station on my way to work dropped 4cents overnight to $1.74!
It has to be some sort of conspiracy AaAaArrrrrggrgrghhhh!!!!
The price of oil always seems to be high in Britain, especially by the time it reaches the petrol pumps. While the price fluctuates, the price of a gallon tends not to reflect any price cuts, just increases. This is a huge bone of contention in Britain at the moment along with the price of gas and electricity, which are subject to the same non-fluctuations!
