MORRISONS has been hit by tech issues leaving customers paying more at the till.
Angry shoppers have taken to social media to complain after discovering their Morecards - which give discounts on products - do not work.
One disgruntled shopper said they ended up paying 69p for carrots instead of 10p because of issues with the service.
While another said: "[Morrisons] What's wrong with your more app? I did my shop this morning and was told it wasn't working? and the money should be return to my account over the next 24hrs?"
A third said they reckon they had been left around £20 "out of pocket" because of the issue.
Reports on Downdetector also show 151 customers have flagged an issue with their Morecard.

The majority have reported issues with the Morrisons More App, which gives customers digital access to their loyalty cards.
The Sun has approached Morrisons for comment.
It comes just two days before Christmas, with many shoppers rushing to stores to do their festive food shop.
Today is also one of the last full trading days before the holiday as many grocers shut early on Christmas Eve to give staff a break.
