Safeway and Asda have both moved up the chart to put the pressure on Morrisons.
Safeway now stands just three percentage points behind the chain.
Asda is particularly strong on alcoholic drinks and has a number of gondola ends which are devoted to price promotions.
As expected, alcoholic drinks and confectionery remain at numbers one and two respectively, still with 13 percentage points between them. They have, however, pulled further ahead of the remaining categories.
Price promotions have become increasingly dominant within the alchololic drinks category and a larger number of floor stacks are being used to highlight the promotions.
Household comes in as a new entry at number three.
Cadbury's reasserts itself in the brand chart this week reclaiming the top spot. Nestlé and Terry's follow and, together they make up the top three.
Each of these brands has a number of gondola end sitings along with off-fixture displays. Boddingtons and McVitie's both come in as new entries at numbers eight and nine respectively. While Boddingtons focuses on price promotions, McVitie's features a number of buy one get one free offers.
In the own label chart alcoholic drinks and cakes and biscuits both move up to share first place.
This is the second consecutive week cakes and biscuits has moved up the chart, due in part to a number of promotions on boxed and tinned biscuits.
