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 31 August 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 Sainsbury's 6.1% dearer.
