How prices are collected
Cuugo records online shelf prices for Woolworths, Coles, Aldi and IGA daily. The Index freezes each store's prices for the basket every Friday morning (Melbourne time). The price used is the price a shopper would pay that day — if an item is on special, the special price counts. For each item we match the closest available product at the stated pack size at each store; where pack sizes differ, prices are compared on a per-unit basis against the reference size.
Out-of-stock items
If an item can't be matched at a store in a given week, that store's total is published with the number of missing items clearly flagged, and is not treated as directly comparable to complete totals for that week. We don't substitute a different product, and we don't silently carry forward old prices.
Changes to the basket
The basket composition is locked. An item is only ever replaced if a product is permanently discontinued, and any such change is recorded here, dated, with the reason.
Independence
Cuugo is not affiliated with, sponsored by, or paid by any supermarket. The Index is generated automatically from the same public price data that powers Cuugo's grocery price comparison.
