Motorists can save £5 on the cost of filling up by joining the cashback site.
Motorists can offset some of the recent increase in fuel price by taking advantage of a new cashback promotion.
Voucher site Topcashback will pay £5 cashback to anyone who signs up for their service and spends at least £10 on petrol or diesel.
The offer expires at midnight on 17 August, so make sure you visit the pumps before then.
Cashback on fuel: how it works
The offer is only available to new Topcashback members, meaning existing members will sadly miss out.
When you next fill up (spending at least £10), make sure you keep hold of the receipt.
Take a photo of it, being sure the date, amount and name of the forecourt are all visible.
You'll then need to sign up to Topcashback using this link (it's vital you use this or you won't get your cashback) and upload your receipt before midnight on August 17.
Topcashback says your £5 cashback will arrive in your account within 14 days.
