WEM Price Index · basket 2026-08 · monthly, first working day
Which retailer is cheapest, on the same basket?
A fixed basket of 16 everyday products, priced across UK retailers from WEM’s tracked offers — the same data WEM’s own comparison pages run on. The basket is pinned in code and versioned; an index whose contents quietly change between editions is a different study every month wearing the same name.

Methodology
- Fixed basket of 16 products (version 2026-08), spread across 7 everyday categories. Changes to the basket are versioned and disclosed.
- GBP, in-stock offers only; one price per retailer per item (its cheapest).
- An item counts only when 2+ retailers price it — a “cheapest” with no competitor is a stock list, not a comparison. Dropped items are counted, never hidden.
- WEM earns disclosed affiliate commission when shoppers buy through its links; ranking here, as everywhere on WEM, is by price alone.
