That Waitrose is expensive is a myth.
Used to be but now all essentials are price matched to Tesco.
Two things made me leave Waitrose. First, most was given over to JL department.
If I want a coffee machine, I'll go to JL or buy online. There is never anyone shopping for electricals or household goods in my Waitrose.
Second, the price matching with Tesco. We don't shop at Waitrose for Tesco prices. If we wanted Tesco prices we'd shop there.
Both the above cut out lots of items due to space that only Waitrose had and I miss, such as a particular cheese or fresh shellfish on the counter.
Waitrose did used to be a bit exclusive but no more.
Gasp! I heard a public announcement for staff to come to the checkouts recently. There were never public announcements unless a dog was left in a car on a hot day.
The supervisor would quietly have a word and the wheels would have been put quietly in motion to open another till.
"Madam, would you like to come this way"?
Now it's "this tills open."
I'm open to shopping at Aldi, but having bought two packets of Smoked Mackerel as cheap and them being so full of bones, one being binned I'd never buy anything there again. That was three years ago and haven't eaten smoked mackerel since, from anywhere.
M&S is for busy people who need to put stuff in a microwave or oven.
Waitrose is for people who cook.
