Asda was cheapest for our comparison basket in April 2015

We've added up the price of a basket of branded groceries and found Asda was the cheapest supermarket for April 2015. But who was the most expensive?

Each month, we compare the prices of a selection of everyday groceries from the main online supermarkets. For April, we found Asda was £13.95 cheaper than the most expensive supermarket, charging £131.52 for the 76 products.

But who was the most expensive supermarket this month? The answer is a supermarket who's never been the most expensive for our comparison basket, and you may be surprised by the result.

Supermarket price comparison schemes

Many supermarkets have a price matching scheme. However, these schemes do vary, so to help you out we've put what the major ones are below:

  • Asda checks prices against Tesco, Sainsbury's, Waitrose or Morrisons and it will give you a voucher for the difference if it isn't 10% cheaper
  • Morrisons compares against Aldi, Lidl, Tesco, Sainsbury’s and Asda and gives you the difference in points
  • Sainsbury's has a price match for branded items only and compares against Asda
  • Tesco checks your prices against Asda, Sainsbury’s and Morrisons and will give you a voucher for the difference if it's cheaper elsewhere
  • Waitrose price matches Tesco on branded items and these are the prices it sells for.

Which?'s price comparison basket

Every month we compare the price of between 75 and 100 grocery items at the main online supermarkets Asda, Morrisons, Ocado, Sainsbury's, Tesco and Waitrose. 

We use data from the independent shopping website Mysupermarket and average the prices over the month, including discounts but not multibuys. 

The products are all branded items and include a wide range of groceries - from coffee to cat food, and from beans to bread.
