How we compare prices
We compare the price per kilo, per litre or per item, so pack sizes do not distort the result. Items sold by the piece are only compared with a similar number of pieces. Prices as of 30 September 2026; where a cheaper promotion was running, we use that price.
How the figure is worked out
For each spending category we average the price differences of the products both shops sell, then combine the categories by their share of household spending. The ranking on the Price Monitor page compares all shops at once, through every other shop as well, so it can differ from this two-shop figure; for these two shops the ranking gives Waitrose 12.9% cheaper. Categories with fewer than 10 products both shops sell: oils and fats: 9 products, 4% of the weight. They count at their full share of household spending, like every category, so they can move the figure more than their few products suggest.
