Apparel maker Oxford Industries Inc on Wednesday revealed it quadrupled its third quarter profit as it was boosted by growth with major mass merchants and the continuing rollout of Lands' End product to Sears Roebuck & Co. The Georgia-based company said its net earnings rocketed 410 per cent to $6.9 million, or 92 cents a share, from $1.4m, or 18 cents a share, in the year-ago period on the back of a 40 per cent jump in net sales to $209m from $149.5m in 2001.
