Yes BIWI, it certainly adds up easily in Waitrose, especially if you're buying booze like DP does all the time. I think their veg last longer and their meat is better quality (though not as good as the butcher's), and the essentials stuff I find about the same price as Sainsbos. I may be deluding myself, though. 
Still feeling shite, but the visual stuff not quite so bad today.
