A MOTHER-of-two is fuming at supermarket giant Asda after falling victim to a blunder on its website, which wrongly told her she was entitled to free groceries.

Candy Ayles, of Norcliffe Close, East Howe, Bournemouth, was shopping online on Saturday.

She went to the website’s checkout to pay for £17.50 worth of groceries but was told she was entitled to a £75 discount on her shopping.

The single mum, who has a two-year-old son called Lucas and a four-year-old daughter called Connie, said: “I decided to go back and do more shopping to take advantage of the offer.

“But the next day Asda telephoned me saying it had made a mistake and wanted the money back.

“It’s unfair and I’m very annoyed because I don’t have that kind of money. At the moment I am looking for somewhere else to live so every penny counts.”

She said the supermarket initially offered £5 off her next shopping bill and free delivery.

But the company contacted Miss Ayles yesterday to say she would get the £75 discount after she said she complained to trading standards.

The £75 offer was open to first-time online shoppers on Saturday night across the country.

But on Sunday morning some people, including Miss Ayles, who had taken advantage of the deal were either told by phone or by delivery drivers that they had to pay full price for their shopping or cancel and return it.

Miss Ayles, 22, said she had heard more than 1,000 people were affected.

An Asda spokesman said: “We clearly had a keying error that wrongly gave people a discount at the checkout online. We put that right within hours. There’s no concern about site security.

“We’re bending over backwards to recompense the small number of shoppers who wrongly got offered the discount voucher. We’ll be giving them free delivery and a discount off their asda.com shopping.”
