Sainsbury's offers 10 Nectar points per litre of fuel

Motorists who fill up at Sainsbury's in October can collect 10 Nectar points for every litre of fuel they buy.

The supermarket said the offer works out to an equivalent cash discount of 5p per litre.

There is no limit to the number of times a motorist can fill up, but the promotion will only run for one month.

Sainsbury's announcement marks the latest salvo in the ongoing fuel price war between the big four supermarkets - Tesco, Sainsbury's, Asda and Morrisons.

Data from the AA showed the average price of petrol fell back below 110p a litre yesterday for the first time since March, having been as high as at 117.28p in June.

Responding to today's Nectar point offer, Sainsbury's head of fuel Avishai Moor said: "This is one of the biggest points giveaways we have ever done and will really boost our customers' Nectar balances in the run-up to Christmas.

"We know that fuel can be a big expense, so we are happy to be able to reward motorists in this way."
