Hi, I don't think we have Waitrose in North Wales, is it a southern chain? I am just off to stock up on basics. Going to Aldi as I find them very good for most things especially store cupboard stuff.
Also their facial wipes are excellent at 77p. Their green grocery section is improving all the time too. I usually go to Aldi or Lidl first and then if I need something I can't get there I go to Tesco or Asda.
These days I don't do a 'big shop' anymore as there are only the two of us. Also where we live there is a fabulous butchers as I don't buy much supermarket meat.
