I have been a regular customer for around 7 years, since delivery began in my area.
I was unable to get deliveries for about 3 months during the first lockdown. No problem as other people needed them more.
Really wasn't keen on the switch to M&S because I loved the Waitrose range and expensive ready meals aren't my thing.
We were told that an equivalent would be available for most products.
That is certainly not the case and lots of other brand products have disappeared.
It is also far more expensive and very few offers. One item I buy regularly used to be 2 for £7 now they are £4.40 each.
I really miss Waitrose essentials 
Anyone else jumped ship?
