Multi-price discounter B&M’s (BME) third quarter and Christmas trading update (12 Jan) will reveal if momentum has continued with the multi-price value retailer, a beneficiary of the cash-strapped shopper’s quest for value. New customers have been driving strong growth at B&M. Building on this it is opening new stores in the UK and Germany and is a recent entrant into the attractive convenience shopping space following last year’s acquisition of Heron Foods.
