The best supermarket for everyday groceries is the one that offers a good total price on the items you actually buy, stocks what you need, and fits your routine. Compare a repeat-purchase basket at nearby stores, then weigh the real trip or delivery experience. No chain can be named the cheapest everywhere without current, local, like-for-like price data.
How to compare supermarket prices fairly
Start with a short list of groceries you buy regularly, using the products and quantities that match your household’s actual use. Compare the total cost of that same basket at realistic local options, using the prices you would actually pay. This gives a more useful comparison than judging a store by one advertised deal or a handful of shelf prices.
When packages differ in size or format, compare unit prices—the cost per standard measure such as kilogram, litre or item—where the measures are equivalent. The Australian Competition and Consumer Commission says unit prices help consumers compare similar products (ACCC guidance on grocery unit prices). Unit pricing can also help you check promotions or spot when a product’s quantity has changed, but it is useful only when you compare like with like.
- Use the same basket and quantities for each store.
- Compare similar products and check package sizes.
- Use unit prices when the products and measurement units are genuinely comparable.
- Consider whether a larger pack will be used before it expires. In UK consumer research, some participants found bulk comparisons less suitable for fresh food when waste was a concern (CMA consumer research and unit-pricing analysis, 30 January 2024).
When unit-price labels do not line up
Unit-price rules and displays vary by country, and labels can use different measures or be difficult to read. Canadian federal guidance describes voluntary displays outside Quebec and notes that they were not standardized when the guidance was written (Innovation, Science and Economic Development Canada guidance). The UK Competition and Markets Authority has also reported inconsistent measures and promotion-related display problems (CMA unit-pricing case page). If labels differ, check package quantities and calculate a common unit before comparing; do not treat unlike measures as equivalent.

Obligations are jurisdiction-specific. Australia requires most supermarkets and online grocery stores to display unit pricing under the applicable code, while requirements elsewhere differ. Singapore’s competition regulator describes a unit-pricing pilot at selected participating outlets, not a universal display practice (CCCS About Unit Pricing, updated 28 September 2026). Check the rules and labels where you shop.
How to judge loyalty prices and promotions
First establish which price applies to you: a loyalty price may require membership or other qualifying steps, and the non-member price may be higher. Compare the qualifying price with similar products at other stores, then include it in your basket total rather than assuming that a member deal makes the whole shop cheaper.

- Compact for travelling
In its 2024 UK review, the CMA analysed around 50,000 grocery products with loyalty-price promotions and found very little evidence that retailers inflated usual prices to make deals look better. It also cautioned that loyalty prices are not always the cheapest option, so comparison shopping still matters (CMA announcement, 27 November 2024).
The same UK review found that 69% of survey respondents said loyalty pricing had not changed how much they compared supermarket prices, while 24% said they compared more. Respondents regularly shopped at an average of three supermarkets, a survey finding rather than a recommendation to make multiple trips (CMA executive summary, 27 November 2024). Whether another shop is worthwhile depends on the extra travel, time and effort for your household.

A broad range matters only if it includes the items you use: regular staples, preferred brands, dietary options and household essentials. Assortment can differ between locations, and an online service may not carry exactly what a physical branch does. Check the specific branch or delivery service rather than relying on a chain-wide assumption.

Compare the actual effort of shopping at each option, not just the distance on a map. For an in-person shop, consider travel time, opening hours, accessibility, parking or public transit. For an online order, check delivery slots, minimums and fees. These details vary locally, so verify them with the store or service.
Rank #4
A lower basket total may not be worth a longer trip or an unsuitable delivery window; the right trade-off depends on your schedule, mobility, transport and household needs. If two stores are plausible, compare them against the same decision criteria:
Quick Recap
Best Value
- It can be a gift option
- Comes with secure packaging
- Helpful in various ways
| Factor | What to compare |
|---|---|
| Basket price | Total for the same repeat-purchase list at prices available to you now. |
| Unit value | Price per comparable weight, volume or item, where labels use equivalent measures. |
| Loyalty terms | The price you qualify for, plus any membership requirements and offer conditions. |
| Selection | Whether the specific branch or delivery service stocks your regular items. |
| Convenience | Travel time, access, hours, delivery availability, minimums and fees. |
A practical way to make the choice
- List your regular purchases. Include the quantities your household typically uses, not an idealized bulk shop.
- Choose realistic local options. Consider stores you can reasonably reach or delivery services available to your address.
- Compare the same basket. Record current prices and use comparable unit prices for similar products in different package sizes.
- Apply eligible offers. Use loyalty prices only if you meet their terms, and compare them with alternatives.
- Check stock and logistics. Verify that the specific store carries your needs and that its hours, route or delivery arrangements work for you.
- Choose the best fit for your routine. Decide how much a price difference matters relative to time, travel, convenience and the risk of buying more than you will use.
