I only really live around a Tesco & Sainsbury's, so I was under the impression that generally the 'non-clubcard' prices were more or less in-line with competing supermarkets for most items? Is this wrong? My only other frame of reference really is Sainsbury's which I've known to overprice things anyway.

That's the impression they want to give you. The non-clubcard prices are significantly higher than Waitrose, Asda and Sainsburys.

I've just stopped buying anything that displays a Clubcard price. It's pesky but doable for now. That may change, of course; I don't see them getting much pushback on this so I expect them to keep doubling down.

A non-Tesco supermarket is going to be a priority next time I move.

Wish I had one... Waitrose is my other option, so yeh.......

Waitrose is considerably cheaper than Tesco without a clubcard.

No way, Waitrose is incredibly expensive everywhere I lived compared to Tesco, Sainsbury's, and Asda. Up there with M&S. But I guess it also depends on your typical basket...

Stick to the Essential lines and it's fine. The quality is also better than the generic fake brand crap that Tesco sell and it's the same price or better. Waitrose essential baked beans for example are waaaay better than any others.
