Macy's has reported its fourth consecutive quarter of comparable sales gains, a positive trend attributed to merchandise overhauls and improved customer service, leading the company to raise its annual outlook. In the first quarter, comparable sales rose 3%, marking the strongest first quarter in four years, with Bloomingdale's stores achieving a record first-quarter sales volume with a 10.2% increase, and Bluemercury sales up 6.4%. Despite broader economic challenges like high gasoline prices, CEO Tony Spring noted that customer spending has not noticeably decreased, attributing this to Macy's enhanced assortment and perceived value, with strong sales in categories like prom dresses and men's shoes, though furniture sales remain disappointing. The company posted a net income of $63 million for the quarter ended May 2 and now expects annual net sales between $21.5 billion and $21.75 billion.
