Asda hung on to the cheapest retailer title this week, pipping nearest rival Tesco to the post by 75p, in a week where pricing activity was minimal among the retailers.

Despite being the cheapest retailer, Asda made no reductions this week. Lenor concentrated fabric conditioner was up 21p after a promotion ended and Schweppes Tonic Water was up 3p.

Tesco crept up one place to second. It introduced two promotions, reducing celery 28p and frozen forest fruits 50p, while promotions ended on the Seeds of Change organic Bolognese sauce, up 48p, and Young’s Premium Scampi, up 99p.

Sainsbury's also moved up the rankings. Its trolley cost just 40p more than Tesco’s. It began a promotion on PG Tips pyramid teabags, which were down 12p, and made a 6p hike on white rolls. Morrisons lagged behind at fourth after sliding two places. There was just one hike, on oranges, which were up 8p. It reduced three items – Batchelors Super Noodles and McCain Home Fries Oven Chips both by 5p, and PG Tips pyramid teabags, down 13p.

Waitrose resumed its usual fifth place with a trolley costing almost £8.50 more than Asda’s. It increased the price of pears by 3p/kg and made a 13p reduction on PG Tips pyramid teabags.
