“Never knowingly undersold” has become harder to defend as competition from online retailers has become ever tougher.
The new chief executive Sharon White told the Sunday Times she expected the price pledge to go.
She said it could be replaced with “Fair value for all”.
The department store chain has already announced the closure of eight stores including its flagship Birmingham site which only opened five years ago as it struggles to adapt to the challenges arising from the pandemic. This year between 60% and 70% of John Lewis’s sales are expected to be online, compared to 40% last year.
Even before Covid-19 hit, the chain, which is run as a partnership, had warned it might not pay the usual staff dividend as competition ate into profits.
Ms White told the Sunday Times the chain needed “more inspiration, surprise, fun” and that it would compete by “curating” items in store better. John Lewis would focus less on women’s fashion and get rid of travel and spa services. Instead it would offer more financial, home and garden products, she said.
Ms White said she wanted to reaffirm John Lewis’s reputation as a socially responsible retailer and “shout more” about its values.
Since 1925 John Lewis has promised to refund the difference in price, to any shopper who could find an item cheaper elsewhere within 28 days.
However the commitment has never applied to sales from internet-only retailers, which have lower costs and often undercut the High Street on price.
John Lewis indicated earlier this year it was reviewing the promise. It said “fair value” would still be central to its ethos but “in a more modernised form”; it hopes to have a new slogan in place by October.
“Never knowingly undersold is from another era,” said Catherine Shuttleworth, founder of retail marketing agency Savvy.
“She’s got to correct the course on that. They’ll be out of business if they do that in a world where Amazon change their prices every minute.”
The business is also facing challenges in its Waitrose grocery arm. Next month its long-standing link with delivery service Ocado comes to an end at a time when customers are queuing to sign up for online shopping.
The scale of the overall challenge should not be underestimated, said Ms Shuttleworth.
“It’s the biggest crisis in the history of the partnership… There’s got to be some significant changes to make sure it survives for the future.”
