Off-price retailer of casual apparel, Factory 2-U Stores Inc, has posted a 3.9 per cent slip in July same-store sales and a 4.7 per cent fall in total sales for the month due to lower demand for men's fashions. The California-based operator of more than 250 stores said total sales slipped to $41.6 million from $43.6m in the year-ago period, with second quarter sales down eight per cent to $128.1m from $139.3m in 2001.
