Epic fail

A common misconception; waitrose is expensive. It isn't. For most basics it works out cheaper than, or better quality for same price than sainsburys.

Sainsburys is incredibly bad value for non-offers.

"I shop at Waitrose because they reduce out of date items at more predictable times of day than other supermarkets"

This is completely wrong.

please give examples where waitrose is cheaper than sainsbury's basic range.
