(Reuters) - TJX Cos Inc <TJX.N>, operator of off-price retailers T.J. Maxx and HomeGoods, reported better-than-expected quarterly comparable store sales as its discounted offerings continue to attract shoppers.

Shares of the company, which also owns Marshalls retail chain, were up 1.6 percent at $75.40 before the bell on Tuesday.

The company's comparable store sales rose 5 percent in the third quarter ended Oct. 29. Analysts on average had expected comparable store sales to rise 3.6 percent, according to Consensus Metrix.

TJX and other off-price retail chain operators have been growing quickly as bargain-hungry shoppers turn away from department stores and other mall-based chains.

The company sells home furnishings, apparel and accessories of well-known brands including Dolce & Gabbana and Versace, at prices 20-60 percent lower than those at most retailers.

TJX said its net sales rose to 6.9 percent to $8.29 billion, beating the average analysts' estimate of $8.22 billion, according to Thomson Reuters I/B/E/S.

However, net income fell to $549.79 million, or 83 cents per share, from $587.26 million, or 86 cents per share, a year earlier, due to a pension settlement charge and a loss on early extinguishment of debt. Excluding these items, the company earned 91 cents per share.

Analysts on average had expected a profit of 87 cents per share.
