For simplicity we have rounded the actual figures to the nearest significant number and to be fair to our competitor, we have rounded Tesco's number down, and their number up. Actual figures may be found in the content below.

The prices published are representative but may not always be identical to what you will see in your local store.
The matches we make are based on stringent rules which are themselves based on the rules for comparative advertising set out by the UK rule making body for advertising standards, the Committee of Advertising Practice.
We compare prices with our competitors by creating matches between products which are similar in terms of brand and quality. Manufacturer brands (e.g. Walkers, Kelloggs, Coca Cola) are compared on an exact match basis.
When comparing own brand products with competitors' own brands we make sure we only compare on similar quality e.g. we compare our Value with their equivalent Value products, our Standard with their equivalent Standard products and our Finest with their equivalent Finest products.
If you want to see just how low our prices really are, simply search for any product in the Price Check box and see how we stack up!
We always aim to make a fair comparison between products. If a competitor's own brand product has a pack size differential of less than 10%, we compare prices on an exact match basis. If the pack size differential is greater than 10%, we do not include the product in our comparison.
The comparison excludes products without a match. We do not take into consideration any price savings for multi-buy promotions; we use single item price. Price cut promotions at all retailers are included.
This means we include more than half of everything our customers buy on the day in question.
We try to ensure that the prices displayed on this facility are fair, representative and accurate. However, in a survey of this size, it is always possible that an incorrect price may be quoted.
All products are subject to availability. Some products are only available in selected stores.
On Monday 9th November 2009, we took all Clubcard transactions from Tesco total transactions, excluding transactions from Tesco Express and selected Tesco Metro stores. This amounted to 2,337,805 baskets.
We calculated how much each basket would have cost in our competitor's store by overlaying prices taken from their online data on the same day and identified how many were cheaper in Tesco, how many would have been cheaper in our competitor's store, and how many would have cost the same:
| Competitor | Baskets cheaper at Tesco | Baskets which would have been cheaper at competitor | Baskets which would have cost the same | Baskets in the sample size | Baskets excluded from the sample* |
|---|---|---|---|---|---|
| * relates to baskets where no items in the basket matched. | |||||
| Asda | 1,064,465 | 717,621 | 287,967 | 2,070,053 | 267,752 |
Prices for Asda and Sainsburys were taken from Asda.com and Sainsburys.com respectively.
Prices for Morrisons were independently collected in three stores nationwide. If a product was sold out in a particular store, the checkers recorded the price on the shelf edge label. If a product was price marked on pack and the shelf edge price was different, then the lowest price was taken. If prices differ between the three stores then the most commonly found price was used. If there was no common price, the product was shown as "Not Found" (N/F).
