I’D like Tesco to answer this one. Why is unleaded petrol 128.9p per litre one day, then 129.9 the following day?

And, lo and behold, a couple of days later it has risen once again to 130.9p. That’s 2p per litre in two days.

On asking the cashier, the only reply I got was: “We ask ourselves the same thing, it’s nothing to do with us.”

I know prices fluctuate, but surely it doesn’t have to be on a daily basis. I would rather buy at the cheaper price (obviously), and grow tired of the daily rise and fall.
