Nectar is especially bad here. I signed up because Sainsbury’s have ‘special’ prices for nectar card users on many items (presumably they increase the price and then reduce it back down for cardholders). But there was no way to opt out of marketing and tracking.

By contrast when I signed up for Tesco clubcard, even pre gdpr, I was easily able to opt out of tracking. I don’t get targeted vouchers, or any discount coupons, but I still get points and clubcard prices.

How do you know they stopped tracking and didn't just stop giving you vouchers and whatnot?

Good point. Although I should point out the vouchers would be for their benefit not mine - the whole point of supermarket tracking is to entice you into discovering some high margin item you will end up loving. So their motivation to track is reduced.
