This is a heads up for anyone near enough to benefit. Tesco Express Esso in Ongar currently priced Petrol 112.9 and Diesel 116.9.
It's been cheap there for a while due to a local price war, but just dropped stupidly low.
Manager turns up every day to make sure they undercut the local BP... Be giving it away soon :P
Edit: Both now at 109p.
