Loyalty points

Sainsbury's has added a new 'Spend Lock' feature to its Nectar loyalty app that prevents your points from being redeemed without your knowledge. It follows a spate of complaints in recent months from shoppers claiming their points had been stolen.

Costa Coffee loyalty account holders will be moved onto a new membership scheme across the course of this month. Under the revised loyalty offering you'll earn 'beans' instead of points and you can earn freebies more quickly, although you won't be able to redeem rewards on any anything other than drinks. The new membership scheme will also replace the existing one for new joiners from the same date.
