Luxury items, jewelry and products sold online were the fastest-growing U.S. sales categories in the retail sector in May, but weakness in apparel and electronics suggest consumers may still be wary in their spending, according to a report released on Thursday. The strongest sector was eCommerce, which logged its sixth straight month of double-digit gains and 10th consecutive month of gains. Within that, children’s apparel and family apparel showed gains of 30.4 percent and 26.2 percent, respectively. – from Reuters
