SuperValu now occupies the top spot, having seen sales climb by 2.5% over the past 12 weeks, increasing its share of the market to 24.6%. David Berry, director at Kantar Worldpanel, explains: “The grocery market is arguably the most competitive retail sector and the latest figures emphasise this, with the three biggest retailers each within one percentage point of each other’s market share.“This is the strongest growth rate recorded by SuperValu since August 2013, which the retailer has achieved by encouraging more repeat shopping trips. The average consumer has visited the retailer on two additional occasions and spent an extra €16 over the past quarter when compared with last year.”
