Sainsbury’s has dropped below the important £1/litre barrier for unleaded petrol in a promotion launched across the UK today.

Customers who spend £30 or more in store or online up until 4 March will be able to fill up at the low price in the supermarket group’s 298 forecourts.

The supermarket group has calculated that the deal could save a customer driving a family saloon car on unleaded petrol as much as £12.44, compared to what they would have paid in the same week last year.

Roger Burnley, Sainsbury’s retail and operations director, said: For the cost of their essentials, they can take advantage of some of the biggest fuel savings in the market.”

Products that are excluded from counting towards the qualifying £30, include spirits and liqueurs, scratch cards, prescription medicines, infant formula, tobacco and related products, gift vouchers, BT phone cards, E-Topup, savings stamps, postage stamps, National Lottery products, purchases from coffee shops, restaurants and charity products.

The money-off vouchers are valid for 14 days.
