Retailer Co-op is to offer its members £10 off a minimum shop of £40 following disruption caused by a recent cyber attack.
The grocery chain said it had not yet completely recovered from being targeted by hackers last month, which resulted in a significant amount of customer data being stolen.
Although the offer appears generous, one analysts said the majority of customers do not spend £40 or more per shop, so it would not appeal to many people.
The one-off deal, which runs from Wednesday for a week, is open to existing Co-op members, and a shoppers wanting to sign up, but not to staff.
A Co-op source said since stock levels had returned to normal over the past few weeks, there had been a strong pick-up in sales.
The offer was to show that the Co-op was “on the front foot” ahead of summer trading, the source told the BBC.
But retail consultant Catherine Shuttleworth said the offer indicated that members may have started to shop elsewhere and was an effort from Co-op to try to get them back.
Co-op said if members spend £40 or more in store, they will get £10 off their shop.
