How we measure this

We price the same 40 products every week at every store. For each product we take the cheapest option, including any offer running that week. The index is the average of those weekly baskets, set to 100 in the first month we measured.

A store that could not price all 40 products is scaled up to the full basket. That total is an estimate. The table below shows how many of the 40 we found at each store, so you can see which totals to read with more care.
