I do the weekly shop in Waitrose and the other half insists on it anyway, plus we get a lot of organic stuff. I've not bought much food from Aldi/Lidl but from what I have, a lot of it has been excellent. Lidl has tons of traffic and the specials are normally scattered all over the place but the food side is normally tidy. My local (well, not so local) Aldi is immaculate inside. You can get same brand stuff much cheaper at Aldi/Lidl than Waitrose, that's for sure. And Waitrose customer service is great but their products aren't always up to the mark.
