Total sales grew by four per cent to £929 million during the 13 weeks to May 31, compared with the two per cent fall predicted by analysts.
During its first quarter, Argos opened three stores and closed one, taking its total portfolio to 709 outlets from 683 one year ago.
Like-for-like sales were flat, however, internet sales continued to grow by around one-third, and represented 22 per cent of its total sales.
Parent company, Home Retail Group, attributed the growth to an increase in demand for consumer electronics.
Terry Duddy, chief executive of the Home Retail Group, described Argos’ performance as “resilient”.
"While the consumer outlook remains challenging, we approach it from a position of both financial and operational strength, and at this early stage our expectations for the full year are unchanged," he added.
