Most U.S. retailers reported weak sales in March as consumers, concerned about growing economic problems, limited their shopping to food and other essential items. As the country's major retailers reported sales figures on Thursday, it was clear that consumers remained focused on buying basics at discounters and wholesale clubs and ignored the mail-based chains for clothing and other non-essential purchases. Wal-Mart Stores and Costco Wholesale Corporation were among the best performers, but March was another weak month for many other retailers who reported sharp declines in sales. According to preliminary figures, 17 retailers missed sales expectations, while only six beat estimates. The count is based on sales at stores open for at least a year, and it is considered a key indicator of a retailer's health.
