We compare prices on a basket of popular branded items at Asda, Morrisons, Ocado, Sainsbury's, Tesco and Ocado every month

Asda was the cheapest supermarket for June 2016 in our monthly price comparison, comfortably ahead of its rivals.

We compared the price of 78 branded products in Asda, Morrisons, Ocado, Sainsbury's, Tesco and Waitrose for the whole month of June.

Asda was the least expensive at £156.44 - the same items in the next-cheapest supermarket cost £162.38, while in the priciest of the six they cost £173.95.

Supermarkets in the news in June

Amazon launched its own fresh food delivery service earlier in the month, providing competition for the supermarkets - although the service is only available in parts of London so far. 

Meanwhile online rival Ocado posted good financial results, with sales, revenues and profits in the 24 weeks to the end of May all rising by more than 10%. Tesco also had good news on that front, as it recorded its second straight quarter of sales growth. Waitrose, however, saw profits drop by 17% in the year to January.

Convenience store chain My Local - made up of 130 stores which belonged to Morrisons until October last year - went into administration last week. Morrisons said that if My Local stores close, it will re-employ any ex-Morrisons staff who were transferred to My Local in October.

And Morrisons, Asda and Iceland have been named as the grocers who treat their suppliers the worst, according to a report by the industry watchdog the Groceries Code Adjudicator.

How we compare supermarket prices

To compare prices, we start each month with a list of over 100 popular branded products each month, which are likely to be sold in all six supermarkets we cover.

Using data from the independent shopping website MySupermarket, we calculate the average price - including discounts, but not multibuys - for each item across a whole month. Those are added up to get the cost of the basket.

If a product hasn't been sold in one of the six supermarkets during the month, then it's removed from that month's basket.

Supermarket price comparison schemes

Many supermarkets have a price matching scheme, where they compare their prices against other supermarkets. They will often give you a voucher for the difference, if your shopping would have been cheaper elsewhere.  As the schemes vary, we've rounded up the differences below. 

Tesco has changed its price comparison scheme and now deducts money at the till or as you pay the bill online, so should charge the same as Asda for our basket. However, you need to buy at least 10 items to qualify for the scheme.

  • Asda checks against Morrisons, Sainsbury's, Tesco, and Waitrose. Asda will give you a voucher for the difference if it isn't 10% cheaper.
  • Morrisons no longer has a price match scheme.
  • Ocado price matches against Tesco and will give you a voucher for the difference.
  • Sainsbury's no longer has a price match scheme. 
  • Tesco checks your prices against Asda, Morrisons, and Sainsbury’s. Tesco will deduct the difference off the price of your shop before you pay.
  • Waitrose price matches Tesco on branded items. There aren't any vouchers - these are the prices it sells the items for.
