When the economy is regularly giving you a kicking all across the board and we remain rudderless in the storm what is the point of even the most basic of research into price variations? Sometimes seeing things as they are, in other words having some "knowledge", isn't really all that useful. There are a few things you'd just rather ignore, like the crazy price of petrol. Here's where you can compare prices if you dare. It's hardly a revelation and is arguably pointless as there's no real difference between suppliers.
I had expected BP to be more expensive (though our actual local BP and Shell stations don't figure on this list and they are only about half a mile away) but it's in second place ahead of Tesco. Why don't their automated pumps show up a saving? Anyway I quite like the fruit and bakery departments in Morrisons but it's over at the Gyle, all potholes and bus lanes too. One day we'll all have EVs I suppose and we'll worry about the prices of charging as we grapple with range anxiety and software upgrades. Until then it's just buttons.
