Done Aldi and Lidl in another thread and now for the other end of the scale...
The whole concept of Waitrose. Just why? Paying more for exactly the same items just because it's Waitrose.
I kind of get they may try and advertise their own brand stuff as high quality (whether it is, is another thing) and charge it at a premium but normal branded stuff e.g. Yorkshire Tea, just costs more for no reason whatsoever.
Why would anyone, even rich people shop there out of anything other than it being the closest shop and they need to grab a few bits?
