SAN FRANCISCO, Nov 3 (Reuters) - Overstock.com Inc (OSTK.O) posted a narrower quarterly net loss on Tuesday that met Wall Street estimates amid higher revenue and more efficient marketing by the online retailer.

The company's shares rose 3 percent after hours.

A net loss in the company's third quarter was $787,000, or a loss of 3 cents per share, from a year-ago net loss of $1.6 million, or 7 cents per share.
