Check the groceries you actually buy

Catalogue-wide evidence is useful context, but your list and nearby stores determine your result. Search products, select local stores, and build a list for a relevant comparison.

Methodology

How this comparison is calculated

  1. 1

    Match the same product record

    A product must be represented at both retailers under the same Shoparound record. Products are generally joined through retailer identifiers and barcode-based catalogue matching. Similar substitutes and private-label equivalents are not treated as identical.

  2. 2

    Keep current, available observations

    For each retailer and store, Shoparound takes the latest recorded row only when it was marked available and checked within the past 14 days.

  3. 3

    Calculate an effective item price

    The regular recorded price is used unless the row has a valid special price and quantity threshold. Multi-buy totals are divided by the threshold to give a per-item comparison. Loyalty eligibility is not inferred.

  4. 4

    Compare retailer medians product by product

    The median store price is calculated separately for each retailer. This stops a retailer represented by more stores from automatically carrying more weight. A tie means the medians match to the nearest cent.

What this analysis does not prove

It is not a weighted grocery basket and does not show which retailer will be cheapest for your list, town, or checkout time.

It excludes retailer-exclusive products, unmatched own brands, unavailable items, delivery or service fees, rewards earned, substitutions, and quality differences.

Recorded specials may require membership or buying a minimum quantity. Store coverage also differs between retailers and can change as importers run.

These are shoparound database observations, not live retailer checkout quotes. Confirm the final price and offer conditions with the retailer before purchasing.
