Sainsbury's has proved you can not only 'Live Well For Less' but also with a clear conscience by emerging cheapest in our special Green Grocer 33 pricing survey.

The basket this week included Fairtrade, free-range, organic, and recycled items and also took into consideration sustainability, packaging and food miles. Sainsbury's delivered a basket costing £61.06, 34p cheaper than Morrisons at £61.40. Asda was 17p behind Morrisons while Tesco and Waitrose trailed in fourth and fifth places respectively.

Sainsbury's this week switched its peanut butter jars from glass to plastic, in a move it said would cut carbon emissions by more than 150 tonnes a year.
