Sainsbury has fixed its online home delivery service, the company told just-food yesterday.

“We are pleased to advise customers that our home delivery website will be up and running after 6pm tonight (19 June) and will be accepting new orders and amendments to existing orders.  Deliveries will resume from 8am on Saturday morning,” a spokesperson said. 

A technical glitch mid-week at Sainsbury’s online shop meant that the retailer has been unable to process tens of thousands of orders.

Asked how many orders were affected, the company said: “On average we serve 90,000 a week and we estimate this will have directly impacted under one third of customers – all day Wednesday, Thursday and Friday.”

The company has apologised to customers and has contacted the majority of customers who were expecting a delivery.

Sainsbury’s told just-food that it was unable to put a figure on the financial loss this will cause, stating: “It’s impossible to quantify.”

When the group delivered its first quarter trading statement yesterday the UK retailer said online sales were up 40% year-on-year.

The spokesperson added that the company had spent just over 48 hours fixing the problem and the website has been thoroughly tested.

“At every stage, decisions have been made based on our ability to serve our customers and offer them the best possible customer service,” the company said.
