Tesco has rolled out its Delivery Saver offer which allows online customers to save on delivery charges by signing up to a subscription service nationwide today.

The new offer allows Tesco shoppers to receive free delivery for a three-month or a six-month period.

Shoppers signing up for six months could save up to £100 on delivery charges, based on one £6 delivery per week and one extra delivery for a special occasion.

The nationwide roll-out of the Delivery Saver follows a successful trial of the service South West, covering 37 stores.

The move will put pressure on online grocery rivals Ocado which launched its similar Savings Pass last year and has reported strong uptake on the loyalty scheme.

Tesco claims to be the world’s largest online grocery retailer and has sales of £2bn through the channel.

Internet retailing director Ken Towle said: “We listened to what our customers told us they wanted, and Delivery Saver is the result. It’s simple to use and will save money at a difficult time for many families. Customers can choose from all available delivery slots, so shopping arrives at the most convenient time.

“Best of all, if you get regular home deliveries it will quickly pay for itself – and the more you use the service, the more you save.”
