Sainsbury's is introducing Nectar Prices, a new loyalty initiative which will give all 18 million Nectar customers big savings on a wide range of products, including some of Britain's favourite brands, when checking out in Sainsbury's supermarkets or online.

The retailer is focused on keeping prices low and customers shopping in Sainsbury's supermarkets or online will get discounts on over 300 items initially, spanning household products, pet food and confectionary, with Nectar Prices, when using the Nectar app or card at checkout. The supermarket insisted on April 11 that Nectar Prices will expand into even more categories, ensuring customers get great offers on a variety of items throughout the year.

Nectar customers will be able to access significant savings on products from laundry detergent to cereal, with selected items at half price. For example, customers can expect to pay the following:

• Ariel All-in-1 pods washing liquid capsules original (39 washes), £5 normally £10.50
• 24x330ml Coke Zero, £5 normally £10
• Nescafé Gold Blend coffee 200g, £4 normally £8.10
• Oral-B Pro 3 3500 Cross Action Black & Travel Case, £45 normally £100

All existing Nectar customers need to do to benefit from Nectar Prices is scan their app or swipe their card at the till to save. Customers shopping online will have their discounts applied automatically if their Nectar and Sainsbury's accounts are linked.
