Supermarkets in March
Waitrose announced results including a 24.4% drop in its operating profits for 2014. However, it wasn't all bad news as Waitrose's revenue actually increased and its share of the market is 5% higher than a year ago, according to Kantar. The drop in its profits was the result of lower prices and Waitrose said it had in fact attracted 400,000 more customers a week in 2014.
Morrisons also shared its results and said that it had had another year of falling sales. It announced that it will close 23 under-performing M Local stores.

Supermarket price comparison schemes
The main supermarkets all have some kind of price matching scheme, which means they compare prices against some of their competitors. They will often give you a voucher if your supermarket shop would have been cheaper elsewhere.
However, these schemes do vary. So to make sure you know the difference between them, we've put what the major ones are below:
- Asda checks against Tesco, Sainsbury's, Waitrose or Morrisons and it will give you a voucher for the difference if it isn't 10% cheaper,
- 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.
For our supermarket comparison basket research, we use data from the independent shopping website Mysupermarket and average the prices over the month, including discounts but not multibuys. The items are all branded.
