IT'S column time, and this week Sedgemoor FM's DJ Dave Englefield has petrol prices on his mind:

I’m confused. I know, it doesn’t take a lot. This time around though I am referring to petrol prices. I remember my Dad putting in £2-£3 of petrol at a time.

He used to drive to Bristol Road because it was cheaper than the one on Taunton Road (that was much closer).

I also remember my older sister’s boyfriend filling up £1 at a time.

Even when I started driving many years later £15 would virtually fill the tank.

This isn’t leading to a moan about the price of petrol but more the way it’s priced. For years it has been the practice of stations to display the price of fuel with a point nine at the end (109.9p for example).

Recently I saw one petrol station with a point seven on the end. While I was filling up it set me thinking.

I understand the logic of posting a price of, say, 109.9p as you see it as being less than 110, therefore making it appear cheaper. However, the minimum amount you are allowed to buy is two litres.

What would happen if you were to buy two litres at, say, 109.7 per litre? How much would you end up paying? In theory it should be £2.19 and point four of a penny.

How do you pay the point four? Surely the station can’t round it up as that would mean you overpaying but if they round it down, you are paying less than the advertised price. What is the solution? I genuinely don’t know.

In radio news we have another busy weekend out and about across the area as we are at the YMCA for the Homeless Shoebox Appeal on Saturday, August 12 and also in Burnham on August 12 and 13 for the Viking invasion. See you there.
