Asda

Tesco, Sainsbury's and Asda have today all been fined around £10 million each after the Office of Fair Trading (OFT) found them guilty of co-ordinating price increases.

Asda and Morrisons will become the first major fuel supplier to cut petrol and diesel prices following the recent dip in oil prices.

Tesco plans to launch a nationwide electrical trade-in scheme for old appliances.

Tesco has agreed to re-open a temporary 'double the difference' window after shoppers saw an ad that wrongly said the promotion was back.

Tesco has confirmed its 'double the difference' price guarantee is dead despite an advert it placed in The Sun newspaper yesterday stating it is still alive.

Asda has launched a trade-in service to sell old iPods, mobile phones and other gadgets.

Consumers can now benefit from cheaper prices at the pumps as three major supermarkets have reduced petrol prices.

Tesco has further slashed the benefits of its Price Check guarantee by only paying shoppers the difference if they find something cheaper at Asda, rather than double the difference.

A running enthusiast has found an extreme way to raise money for charity – by rummaging in bins for old Asda and Tesco receipts and exploiting a loophole in the pair's price guarantees.

Tesco has changed the conditions of its price match guarantee against rival Asda in an attempt prevent shoppers using a loophole by buying items simply to get money back, which made some customers hundreds of pounds each.
