It has taken out double-page adverts in the national newspapers today with the headline 'All this for £4 at Morrisons'.
The offer, which runs until Sunday, includes two peppered beef grillsteaks from £1.78 to 50p, four quarter pounder beef burgers from £2.18 to 50p and eight thick pork sausages from 97p to 50p.
British chicken drumsticks and thighs, iceberg lettuce, baby pearl potatoes, four salad tomatoes and 12 white rolls are also included in the offer.
It follows a high-profile campaign by Asda two weeks ago in which the supermarket chain slashed the price of its top-selling items to just 50p as part of a weekend offer.
“We know what our customers need and we are delivering it,” said Martyn Jones, Morrisons' group trading director. “These are great deals on some of our most popular summer products which will give customers a real boost.”
“Our 2,000 Price Cuts in June delivered real savings to our customers and we've doubled that to 4,000. Our summer deal will be another huge saving at a time when our customers need it most."
