Revenue at discount retailer B&M fell by almost 20% during the first five weeks of its new financial year.
The group said its declines pared back to 1.6% in the following eight weeks after the 19.% drop as it stuck by its full-year forecasts for underlying earnings of between £550m and £600m.
The Liverpool-headquartered company, which also owns Heron Foods, added that its like-for-like sales tumbled 9.1% to £1.161bn across its 705 UK stores in the three months to June 25.
