Discounter Big Lots has revealed that its second-quarter revenue for stores open at least two years fell 1.5% compared with the prior year. Total for the period rose 1.8% to $1.15bn (£703.4m) not including the acquisition of Liquidation World, made by the retailer last month. Big Lots chief executive Steve Fishman said that an increase in sales of weather-related products in June and July helped combat a challenging May.
