Locally the diesel prices are coming down and ranging from 169.9 at Sainsbury's in Wellingborough to 184.9 at Waitrose Shell in Rushden, but most are around 175-176.9
Petrol prices don't seem to be dropping though.
I use an Esso fuel card that I got through the Blue Light Card scheme that gets a 4p discount per litre on normal diesel and 6p on super diesel (3/5p on normal and super petrol respectively), so I can pay around 171.9 at the moment.
I also get a copy of every receipt since using the card and that shows me that I've gone from paying about £100 for a tank to the last five tanks costing £105, £121, £155 (!), £142 and £132 although I am only using a tank per month now.
