I went to fill the car up this morning at the BP round the corner from where I live, especially as his price had dropped to 134.9p per litre.
Too big a queue, didn't have the time so drove on.
Just as well
A short time later, I was driving back along the Cannock Road having just picked up the latest EPC and the Somerfield / BP was selling diesel at 125.9p per litre
9p per litre saved - 55 litres to fill the tank - I was a happy bunny
I've never used that forecourt before...but I will in future.
