The reduction has been introduced today (21 Monday) across the supermarket’s 266 petrol stations.
Coupons offering an additional 5p per litre off fuel bills will be issued to customers spending £50 or more in shops or online. A print campaign to back the promotion has also launched today.
Richard Crampton, Sainsbury’s head of fuel, says: “We know that fuel continues to be a big part of many household budgets and we are committed to helping our customers cut down on cost whenever we can. Wholesale fuel prices have dropped across Europe and we are delighted to pass these savings onto our customers.”
Rivals have also stepped up petrol price promotions. Tesco is said to be offering motorists a 10p discount when they buy 18 Andrex toilet rolls, while Morrisons is cutting prices by 12p per litre for customers spending £60 or more.
