Major supermarket is offering £5 free fuel voucher - but there is a catch

A supermarket is offering £5 worth of free fuel to drivers but not everybody can get the deal.

Morrisons customers will get the discount at petrol garages across the UK next week.

But motorists have to be a Vodafone customer in order to get their hands on the £5 voucher.

The offer is part of the company's VeryMe rewards scheme and can be claimed via the app.

Customers can scan their code and apply the discount at their Morrisons petrol station of choice.

But they are advised to be quick if they want money off their next tank, with only 65,000 e-vouchers available.

The voucher is available for use between January 23 and 29.

Drivers are warned that the code is only valid for one hour after being claimed via the app.

E-vouchers can be redeemed at any of Morrisons' 339 petrol stations across the UK.

They cannot be used on self-service pumps, but instead must be presented at the till.

Meanwhile screenshots of the code will not be accepted, according to Vodafone.

Fuel prices remain high in the UK, after the price of unleaded petrol peaked at a record £1.91 per litre in July.

Last week, the average price of petrol was £1.49 while diesel came in at £1.69, according to the latest figures from PetrolPrices.

Drivers can check the price of fuel at their local Morrisons by using the locator tool on the supermarket's website.

Prices can vary, depending on which petrol garage you use to fill up.

Petrol prices can also be checked by typing in your postcode on sites such as petrolprices.com.

Drivers can also look out for other discounts offered at supermarket petrol stations.

Retailers often offer money off fuel for shoppers who spend a certain amount in store.

Loyalty schemes can also save motorists money on their fuel, with some offering as much as 5p off per litre.

One example is BP which offers reward card members one point for every £1 they spend in store or per litre of fuel at the garage.

Once they have earned 200 points, customers are entitled to £1 off fuel.

Texaco members can also save 1p per litre on fuel via its Star Rewards scheme.
