There has been a wave of optimism as Morrisons announced a new deal for motorists. If you spend £60 in store between February 23rd and March 4th, you get a voucher offering 15p off a litre of petrol or diesel at its petrol pumps between March 4th and 11th. The company says it's a better deal than any of its supermarket rivals - including Tesco which is offering 10p a litre off fuel when you spend £60 in store.

The press has been awash with talk of a price war. But the experts say it's not something we should be getting overly excited about.
