Cheaper fuel (South Wales)

[Jamesgt]

My local garage in Abergavenny has been selling fuel for months consistently way cheaper than anywhere else. Sometimes over 20p a litre cheaper than the next cheapest garage. Today the price is £1.57 for unleaded which is 15p a litre cheaper than other garages. What is really going on?

I’m only posting this now as my wife found this article.
