Wal-Mart Stores, the world's biggest retailer, has recorded another record high as cost-conscious consumers turned to the discount chain and apparel sales soared.

In the three months to October, the retailer reported a profit of $1.8 billion, up from $1.5 billion for the same period last year, on sales that rose by more than 11 per cent to $59 billion.

Wal-Mart's clothing sales increased toward the end of the quarter, with like-for-like sales up 3.5 per cent, led by a 4.2 per cent gain at the company's discount store chain.

Chief executive Lee Scott said the retailer expects apparel sales to continue to rise as it expands the company's George clothing line and introduces Levi's jeans to stores next year.

Same-store sales at the Sam's Club warehouse chain rose 0.4 per cent during the quarter, and the division's profit fell 2.4 per cent.

Total sales at Wal-Mart's international division rose 14 per cent, led by sales in Canada and the United Kingdom.

Lee Scott said the company expects the holiday selling season in the run-up to Christmas to see another surge. He reiterated that full-year profit is expected to be $1.76 to $1.78 a share and said fourth-quarter profit would be 53 cents to 55 cents.
