Sainsbury’s has halved the amount of Nectar points you can earn for money spent, a move that has fuelled speculation that frustrated consumers will turn to discount stores such as Aldi and Lidl as a consequence. The supermarket has reduced its Nectar points allocation this weekend, meaning that from this weekend consumers will receive one point for every £1 spent instead of two. They will also no longer be awarded Nectar points for using their own bags.
