Key takeaways

  • ✓Plan a week of dinners and CartSorted pools every ingredient into one shopping list, priced shop by shop.
  • ✓Ingredients pool across recipes, so 600g of flour on Tuesday and 400g on Thursday is one bag — not two.
  • ✓Every line is bought on the best unit price, not the smallest pack, so pack sizes are judged fairly.
  • ✓The cheapest store changes as prices move — we re-check so you don't have to.
Can CartSorted plan a week of meals and tell me what it costs?

Yes. Pick a week of dinners and every ingredient is scaled to your household and pooled into one shopping list — 600g of flour on Tuesday and 400g on Thursday is one bag. Each line is matched to a real product at each supermarket that stocks it, so you can see what the week costs before you go.

Which supermarket is cheapest for a whole meal plan?

Every line is priced at each supermarket in your region and ranked by unit price, not pack size — a larger pack at a better rate wins, and the surplus it leaves is shown separately rather than counted as overspend. You get one recommended shop for the week whenever a store covers enough of the list to name one; when none does, we say so rather than guess. Totals are an estimate built from the shelf prices we hold, not a register total.

How does CartSorted find the cheapest supermarket?

It prices your actual basket across the major grocery retailers in your region and totals each one, so the result reflects everything you buy — not a few well-known items.

Is the cheapest store the same every week?

Not necessarily. Prices move, so CartSorted re-compares to keep the answer current.

How are different pack sizes compared?

By unit price (per 100g, per litre or per item), which normalises pack sizes for a fair comparison.

Do I need an account to compare prices?

No. Browsing prices, comparing stores and the worked example week are all open to anyone. An account is what saves your meal plans and shopping lists so they are there next time.

Each product carries its full price history — the lowest and highest we've ever seen it, and when.

  • Ranked by unit price

    Every list is ordered per 100g or per 100mL, so a bigger box can never masquerade as a better deal.
