I got the email below today.
I unlock each time I go in the store, but yet another obstacle they find to put in the way.
I cann see less generosity with the nectar points going forward.

As you're an active Nectar Sainsbury's shopper we're informing you of changes to the way you access Your Nectar Prices. For your personalised discounts, which will be valid from 25th July 2025, this means:

• You'll need to ensure you're using version 11.8 of the Nectar app or later.

• You'll need to view and unlock Your Nectar Prices in the Nectar app each week before you shop. Your Nectar Prices will refresh every Friday, and you'll need to unlock them each week.

• If you'd like a regular reminder to unlock Your Nectar Prices when they refresh each week, please enable in-app push notifications in your Nectar app.

• From 25th July, you'll be able to use Your Nectar Prices at supermarket checkouts in any store. This is in addition to Smartshop and Sainsburys.co.uk.
