It's not about trust. It's about the fact that in the UK now, you have to have a nectar card to shop at Sainsbury's. Not doing so is a financial mistake in itself.

Many products are deeply discounted just by owning a card. You also cannot use certain features, such as scan-as-you-shop, without them.

Isn't it Tesco rather than sainsbury's that you really need (?) a card for, for now at least?

Unfortunately Tesco's loyalty scheme requires an app, which is far more invasive than knowing I regularly buy cat food at Sainsburys. So I have a Nectar card but not the Tesco app.

I have a Tesco Clubcard (physical card) but not the Tesco app...

Last time I asked for a clubcard they said the only option was to use the app. According the website you can still order a card after registration though. Meh. They're really pushing the app these days.

I found one on the floor. I use that one now.

still getting by with the little plastic tesco barcode card on my key ring. But it's just a matter of time, before I'll need all the apps on my phone.

Like Tesco, Sainsbury's has prices that are exclusive to Nectar card holders.

They also have some personalised prices, where you get targeted special prices if you have a Nectar card.

Not using a Nectar card in Sainsbury's will mean paying more.
