“I didn’t get Clubcard prices on my online shop I collected today – charged full price,” a second added.
Another shopper asked: “How do you access the Tesco Clubcard prices? Went shopping yesterday, scanned my card but was still charged the normal price for loads of items.”
Some customers have said the discount was not applied to their shopping and they paid full price.
The supermarket giant explained the issue only affected a small number of customers who had ordered online and it has now been fixed.
