Online supermarket Ocado has extended its price offensive against Tesco with the nationwide roll out of its Low Price Promise campaign.

The campaign, an extension of its existing ‘Tesco Price Match’ scheme, pledges to beat the price of all comparable Tesco shopping baskets, including branded goods and Waitrose own label products.

“We’ve matched Tesco’s prices on branded goods for many years and now with our Low Price Promise we’re going one step further by giving customers across the country a money-off voucher if we don’t beat Tesco’s prices. As the name says, this is a promise to our customers. Now we won’t just match Tesco prices. We’ll beat them,” Ocado co-founder Jason Gissing commented.

The move follows successful regional trials of the price comparison campaign, Ocado said.
