Sainsbury’s has urged online shoppers to review their receipts after a technical fault caused some customers to be charged full price for grocery orders that should have carried Nectar loyalty card discounts. The glitch, which occurred overnight on Tuesday, affected an unspecified number of deliveries placed the following day.
The supermarket confirmed it is now reaching out directly to all impacted customers to ensure no one is left out of pocket. For many households, the Nectar scheme represents meaningful savings on everyday essentials, making the pricing error particularly frustrating for those who had planned their shop around discounted items.
Shoppers Left Hundreds Out of Pocket
Customer complaints surfaced quickly across social media and consumer forums. One shopper on the MoneySavingExpert forum described placing an order with an estimated total of £82.40, only to be charged £102.34 after substitutions. After going through the bill line by line, they found over ten items charged at higher prices than displayed at checkout, with Nectar discounts absent and multi-buy offers not honored. They urged fellow shoppers to scrutinize their receipts and contact Sainsbury’s directly if the numbers don’t add up.
On X, another customer described a similarly jarring experience. “Excited to get half price leg lamb with my online shop yesterday,” they wrote, “Only for u to charge me full price £22! It seems the nectar discount not working for online orders. Sent reply with driver, still waiting refund… So no lamb & £11 out of pocket.” A separate customer reported receiving a refund email that appeared to fall short of the amount actually owed, adding to concerns that the compensation process may itself be error-prone.
Sainsbury’s Apologizes and Promises Resolution
According to a Sainsbury‘s spokesperson, the issue was identified and resolved promptly. “We are sorry that a brief technical glitch overnight on Tuesday meant Nectar Prices didn’t apply correctly on some of Wednesday’s online orders,” the statement read. “The issue was resolved quickly and we are contacting all affected customers to ensure they are not left out of pocket.” The supermarket has not disclosed the total number of customers affected or the overall value of the incorrect charges applied during the window.
The incident arrives at a time of heightened consumer sensitivity around supermarket pricing. Loyalty card schemes like Nectar have become central to how millions of British shoppers manage their grocery budgets, with many items now carrying two distinct price tiers, one for cardholders, one for those without. When that system breaks down, the financial impact can be immediate and tangible.
According to reports, Sainsbury’s was not alone in facing technical difficulties this week. Lloyds Banking Group encountered a separate glitch that briefly caused some customers to view transactions belonging to other account holders via its mobile app, an incident that raised its own questions about digital infrastructure reliability across major British institutions.
For Sainsbury’s shoppers who placed online orders on Wednesday, the advice remains straightforward: check your receipt, compare it against your expected total, and contact the supermarket’s customer service team if the figures don’t align.
