Morrisons has apologised after customers have been unable to get discounts on their shopping ahead of Christmas after a problem with the More loyalty card.
Some customers have also complained that their online orders have been cancelled.
The supermarket says loyalty card and click and collect orders are mostly affected.
“If More Card prices are not registering, we will apply a 10% discount to the customer’s entire shop,” a Morrisons spokesperson said.
They added that some home deliveries may be arriving late today, and that click and collect customers should wait for an email before going to the stores.
Social media users say their discounts are not working at the till, with one person posting a photo of an error message at the self-checkout, which reads: “We are really sorry some promotions and discounts are not working at this time.”
The Morrisons website also appears to be down, with error messages on some pages suggesting invalid or late responses from servers.
One X user said their Christmas food delivery, which included a turkey, was due to arrive this afternoon.
“I’ve rung customer services who said they couldn’t reinstate the order or offer me a delivery slot and there’s nothing they can do,” they told the BBC.
“I explained to them I’m very unwell, disabled and immunocompromised and I don’t drive and they just said they can’t do anything and offered me a ‘£10 good will voucher’. I really don’t know what I’m going to do.”
On the Morrisons Facebook page, people have also been commenting that Christmas deliveries they ordered a month ago have been cancelled.
“Half my Christmas shopping isn’t coming including the turkey and puddings and they were ordered a month ago,” one person commented under a post advertising discounts.
Others say they have been missing out on large discounts in store.
The supermarket has been advertising heavy discounts on Christmas dinner food, including vegetables, in the last week.
“I’ve just wasted an hour of my life shopping at Morrisons only to find out by checking my receipt that I’ve been charged £40 more than I should because the More Cards aren’t working. No communication at all, so loads have probably overspent without knowing,” wrote one user on X.
Today is predicted to be the busiest shopping day for supermarkets this year, according to retail analysts Kantar.
Sales at supermarkets are expected to reach over £13bn for the first December ever.
Morrisons is the fifth-largest market supermarket in the UK, according to Kantar, with 8.6% of the grocery market in the 12 weeks leading up to 1 December 2024.
