Supermarkets in March 2016

Sainsbury's has agreed a deal to buy Argos for £1.4bn, with plans to move some Argos stores into Sainsbury's supermarkets. The results of our best and worst high street shops survey reveals what shoppers think of Argos shops.

Morrisons, meanwhile, had some positive news. It revealed a pre-tax profit of £217 million, after a £792 million loss in the previous year. The chain had sold off a series of unprofitable stores and it's teamed up with Amazon to sell fresh groceries through the online giant's website.

However, is this return to profitability reflected in what Morrisons' customers think of it? We survey thousands of supermarket shoppers to find out what they think about their supermarket, asking about everything from trolleys to prices.

Supermarket price comparisons

Many supermarkets have a price matching scheme, so they will compare their prices against other supermarkets. They will often give you a voucher for the difference, if your shopping would have been cheaper elsewhere. 

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 ten items to qualify for the scheme.

As the schemes vary, we've rounded up the differences below. Click the links to find out what the supermarkets' customers think of them, and to find out if they have any own-brand Best Buys:

  • Asda checks against Tesco, Sainsbury's, Waitrose or Morrisons. Asda will give you a voucher for the difference if it isn't 10% cheaper
