How to Compare Supermarket Prices & Unit Costs

Find out which supermarket is genuinely cheapest by comparing normalized unit prices (£/100g, £/100ml, and £/item) alongside standard shelf prices.

1. Use the search bar on the home page to look up any product or brand (such as Lurpak, Heinz Baked Beans, or semi-skimmed milk).
2. Switch the sort selector to "Best Unit Value (per 100g/L)" to rank every pack size by its true cost per 100g or litre.
3. Click any product card to inspect its 90-day price history thermometer, UK FSA nutrition traffic lights, and cheaper own-brand alternatives.

How the 2-Store Split Basket Works

See whether doing your entire weekly shop at a single supermarket or splitting between two nearby grocers saves you the most money.

1. Add your weekly staples to your trolley using "+ Add to Trolley" or click "Paste List" to import a list from Notes or WhatsApp.
2. Inspect the Trolley Optimizer sidebar on the right to see all UK supermarkets ranked from cheapest to most expensive for your exact items.
3. Review the "Optimal 2-Store Split" recommendation, which pairs two supermarkets only when the combined total beats the cheapest single store.

Using Clubcard, Nectar, More Card & Lidl Plus Prices

Control whether your price comparison includes member-only loyalty discounts or strictly standard non-member shelf prices.

1. Use the "Loyalty Prices: On / Off" toggle in the filter bar to include or exclude Tesco Clubcard, Sainsbury’s Nectar, Morrisons More, and Co-op Member rates.
2. On any product page, compare the highlighted loyalty price directly against the standard non-member shelf price and the 90-day historical average.
3. Spot products where a "member discount" is simply returning the item to its normal historical price.

Scanning Barcodes, Till Receipts & Recipe URLs

Check prices while standing in a supermarket aisle, audit a paper till receipt after checkout, or turn a recipe into a priced basket.

1. Click "Scan Barcode" on the home page to enter or scan any EAN-13 barcode and see live prices across all tracked UK grocers.
2. Click "Scan Receipt" to upload or paste lines from a supermarket till receipt and see how much you could have saved elsewhere.
3. Click "Import Recipe" to convert BBC Good Food or Mob Kitchen ingredient lists directly into matched supermarket basket items.
