SUPERMARKET giant Morrisons, which has a store in Teignmouth, has apologised after a major computer glitch hit customers.

Shoppers have been unable to redeem discounts on their loyalty cards and Click and Collect and some deliveries have also been affected.

The supermarket offers cheaper prices to More Card members on certain items, and has been heavily discounting Christmas food.

A Morrisons spokesman said: ‘Today we are experiencing some system issues which are affecting our More Card customers.

‘For More Card customers who have Morrisons Fivers to redeem, these will be done manually in store by colleagues.

'All our stores have now made the top 100 More Card prices the regular price, including the 10p veg deal, turkeys, spirits and champagne.

‘And in addition we will give More Card customers an extra 10per cent off their entire shop as an apology.'

The 10 per cent discount will apply today and on Tuesday for More Card customers.

Morrisons added some home deliveries may arrive late, and click and collect customers should wait for an email before going to stores.

Morrisons is investigating the cause of the issues in store and online.
